India-based Neutrino Observatory: Project Report. Volume I

Indirect Search for Dark Matter from the Galactic Center with the Fermi Gamma Ray Satellite

Proceedings of Identification of dark matter 2008 — PoS(idm2008), 2009

One of the possible observation strategy is the targeting of regions where high Dark Matter density is foreseen, such as the Galactic Center. This observation poses a challenge: to disentangle the possible Dark Matter signal from the bright gamma radiation of astrophysical sources. The Large Area Telescope on board of the GLAST satellite provides the best opportunity to date for such a study, because of its excellent sensitivity and angular resolution, as compared to the past satellite-borne detectors. A report of the GLAST LAT Dark Matter Group activities on this topic will be given.

We present the discussions carried out during the workshop on selected topics in the above fields and also indicate progress made subsequently. The neutrino physics subgroup studied the possibilites of constraining neutrino masses, mixing and CPT violation in lepton sector from future experiments. Neutrino mass models in the context of abelian horizontal symmetries, warped extra dimensions and in presence of triplet Higgs were studied. Effect of threshold corrections on radiative magnification of mixing angles was investigated. The astroparticle physics subgroup focused on how various particle physics inputs affect the CMBR fluctuation spectrum, and on brane cosmology. This report also contains an introduction on how to use the publicly available code CMBFAST to calculate the CMBR fluctuations.

Diversity among different populations of a locally common rice (Oryza sativa L.) landrace from north-western Indian Himalayas

Of these, four populations were on-farm managed, assembled from different niche environments, and one population was conserved ex situ and represented static conservation. The 16 STMS primer pairs fully differentiated the inter- and intrapopulation diversity. A total of 72 alleles were recorded with a mean of 4.5 alleles per locus. Population wise, the total number of alleles ranged from 21 to 41, with maximum number of alleles for population IC 548358 and minimum number of alleles for population IC 100051 representing static conservation. A greater number of alleles specific to populations under farmer management could be recorded. Changes in yield parameters also seemed to be affected under farmer management besides other environmental adaptations for qualitative morphological...

This paper has been criticised by Bhandari. In the present note, we show that the criticisms are not valid and only reflect his failure to understand some crucial points.

Because of its ability to distinguish the positive and negative muons, this detector can settle this question. This detector can be used as the far-detector of a long-base-line (6000 to 11000 km) neutrino experiment using the neutrino beam from a neutrino factory in Japan, Europe or USA. While this is envisaged as the second phase of the INO activity, it is clearly a long-term goal since neutrino factories are yet to become a reality. Two sites for an underground neutrino laboratory, where the iron calorimeter detector can be located, were identified. A site selection committee has already prioritised them. Many other experiments such as neutrino-less double beta decay, detection of geo-neutrinos and tomography of the Earth are also possible at such a site. Over the years, INO is expected to develop into a full-fledged underground science laboratory hosting experiments that can exploit its special low background environment and infrastructure, including other disciplines such as geology and biology.

$Figure 6.4: The figure shows the events distribution as a function of the fraction of neutrino energy carried by the muon. The data is a 5 years CC muon neutrino sample, without oscillations. Clearly most events fall in a region with small (£, — E,,)/E,, indicating that the muon carries a substantial fraction of the neutrino energy in most events. Here FE, and E,,, refer to the energies of the neutrino and muon respectively.$

Sample fits to the trajectory for p, = py = 2,5, 7,10 GeV are shown in Fig. 6.10. The corresponding expected and determined values of Rp are shown in Table 6.1. Both methods are found to be reliable.$

$[he quarks have fractional charge and interact primarily through the colour force though hey experience all other basic interactions. Their binding through the colour interaction s what gives rise to the proton, the neutron, nuclei and all other hadrons. The charged eptons do not interact via the colour force, but experience the other three forces of nature, lectromagnetic, weak and gravity. The other building blocks of SM are the gauge bosons hat mediate the various interactions, namely, the gluons, the photons and the W*+ and the 7 boson. The ”Standard Model” (SM) of particle physics is a description of the way particles of matter interact. The SM has twelve building blocks of matter, six leptons and six quarks, and their antiparticles.$

After a brief overview, several aspects of NSIs are discussed, including connection to neutrino mass models, model-building and phenomenology of large NSI with both light and heavy mediators, NSI phenomenology in both short- and long-baseline neutrino oscillation experiments, neutrino cross-sections, complementarity of NSI with other low- and high-energy experiments, fits with neutrino oscillation and scattering data, DUNE sensitivity to NSI, effective field theory of NSI, as well as the relevance of NSI to dark matter and cosmology. We also discuss the open questions and interesting future directions that can be pursued by the community at large. This report is based on talks and discussions during the Neutrino Theory Network NSI workshop held at Washington University in St.~Louis from May 29-31, 2019

Multielectron geometric phase in intensity interferometry

But a similar experimental realization of geometric phase in the context of solid-state electronic systems where the polarization state of the photon is replaced by spin-polarized states of the electron remains unexplored. This is primarily due to the fact that the generation of Pancharatnam's geometric phase involves discrete number of cyclic projective measurements on the polarized states of light and an equivalent cyclic operation on electron spin is way much harder to implement in a solid-state setting. In the present study, we show that the edge states of quantum spin Hall effect (QSHE) in conjunction with tunnel coupled spin-polarized electrodes (SPE) provide us with a unique opportunity to generate Pancharatnam's type geometric phase locally in space which can be detected via electronic current measurements. We show that controlled manipulation of the polarization directions of the SPEs results in coherent oscillations in the crosscorrelated current noise which can be attributed to a multi-particle version of Pancharatnam's geometric phase and is directly related to the phenomenon of intensity interferometry. We demonstrate that the interference patterns produced due to the manipulation of geometric phase in our proposed setup show a remarkable immunity to orbital dephasing owing to its spatially local origin.

We investigated the efficacy and safety of a novel antibiotic-free lock solution formed from gas plasma-activated disinfectant (PAD). Using a luminal biofilm model, viable cells of methicillin-resistant , , , and in mature biofilms were reduced by 6 - 8 orders of magnitude with a PAD lock for 60 minutes. Subsequent 24-hour incubation of PAD-treated samples resulted in no detectable regrowth of viable bacteria or fungi. As a comparison, the use of a minocycline/EDTA/ethanol lock solution for 60 minutes led to regrowth of bacteria and fungi, up to 10 - 10 CFU/ml, in 24 hours. The PAD lock solution had minimal impact on human umbilical vein endothelial cell viability, whereas the minocycline/EDTA/ethanol solution elicited cell death in nearly half of human endothelial cells. Additionally, PAD treatment caused little topological change to catheter mate...

Our interferometer comprises of a single gate, that separates the spin resolved edge states of ν = 2 state. An analog of waveplate (from polarization optics) is realized by exposing the individual edges to nano-magnets over a finite length which facilitates coherent manipulation of the electron spin on the edge. We show that the in-plane rotation of magnetization direction of the nano-magnets results in oscillations observed solely in the cross-correlated noise which arises from two particle interference. Through numerical simulations we demonstrate that our proposal is well within the reach of recent experimental developments of spin manipulations on the QH edge.

Applying a magnetic field locally along the edge leads to a gapped edge spectrum with opposite parity for winding of spin texture for conduction and valence band. Using Pancharatnam's prescription for geometric phase it is shown that mismatch of this parity across a p-n junction, which could be engineered into the edge by electrical gate induced doping, leads to a phase dependence in the two-terminal conductance which is purely topological (0 or $\pi$). This fact results in a ${\mathbb{Z}}_2$ classification of such junctions with an associated duality. Current asymmetry measurements which are shown to be robust against electron-electron interactions are proposed to infer this topology.

In this letter, we address the contribution of mediating LFV leptoquarks (LQ) in ν(ν) − N interactions leading to production of τ 's and wrong sign µ's at MSR and investigate the region where LQ interactions are significant in the near-site and short baseline experiments.
