Although self-adjoint Hilbert-space angular-momentum and momentum operators unitarily generate quc rotations and spatial displacements, no single-quc is a physical 'thing'. Photons, 3 generations of fermions, plus massive vector and scalar bosons- all physicist-deemed 'elementary'-as well as dark matter, galaxies and black holes, within an evolving universe are, we propose, each a temporary 'quc family' that aggregates 8 Noether-conserved quc attributes. No 'thing' is elementary. Here proposed is a thing-devoid 'von-Neumann big bang'-that established a huge but finite and permanent set of speed- c chiral qucs, with 'masses' M h /2τc 2 , where M = 1, 2,... M max and τ is 'universe age'. ('Quc-mass', although not physically-meaningful, has the same dimensionality as any thing 's 'mass'.) Quc- aggregate (thing) creations and disappearances-i.e., 'evolution'-are symmetry- governed by an 8- parameter 'centered-Lorentz' (CL) Lie group. CL's 6-parameter SL (2, c) Riemann-geometric 'exterior' of quc rotations and hyperbolic spatial displacements, has a conserved algebra of quc angular-momentum together with quc momentum times τ. A 2-parameter non-geometric CL- central algebra comprises a pair of discrete coupled and conserved quc attributes-electric charge and 'chirality'. Chirality- without any physics counterpart-renders CL a supersymmetry and provides our present universe with nuclear forces-'strong interactions'. Aggregate evolution, with a fixed and finite set of qucs, proceeds via a Schrödinger equation whose CL-invariant self-adjoint non-diagonalizable hamiltonian has potential-energies dependent on correlated quc electric-charges and 'masses'. Hamiltonian expectation specifies total universe energy. Gravitational and electromagnetic quc- pair retarded-potentials have (we propose) led without ' uncertainty', from a purely 'bachelor-quc' big-bang at τ 0 = G ½ (if h = c = 1) starting-age (~10-43 sec), to the currently-evolving thing-assortment (that includes the reader). Bachelor-quc population continues presently to far-exceed that within things, but the hamiltonian momentarily is binding certain low kinetic-energy quc subsets into 'families'-e.g., chiral quc- pair vector bosons and semi-chiral quc- pair neutrinos. Physical masses, for 3 generations of quc- trio charged leptons and quarks, relate to 'Higgs-cores' that each pairs qucs of zero chirality but nonzero opposite-sign electric charges-of equal 3-valued magnitudes. 1 Introduction Hamiltonian- evolving Gelfand- Dirac-Riemann big-bang quantum cosmology differs profoundly from Einstein's 'general relativity', whose gravity emphasis ignored both electromagnetism and geometrical quantum-universe evolution from a beginning. Pursuing Milne's thinking rather than Einstein's, we here spatio-temporally locate our universe inside a forward Lorentz-Minkowski light-cone. The latter (cosmological, not physical) notion-a geometrically- curved, hyperbolically-unbounded universe-associates to a remarkable Lie group that first received physicist attention in Faraday-Maxwell (classical) electromagnetic theory. 'Special-relativistic' quantum- field-theoretic (QFT) physics-association of 'boosts' to this group, as well as to its SL (2, c) semi-simple counterpart, employs (Feynman) 4-vector momenta-not 4-vector Dirac- coordinates. Cosmological Riemann-geometric (quc- not field) 'boostable 4-vectors' comprise a set of Dirac's coordinates- not of his momenta. This paper recognizes two different meanings for the term 'momentum'. Dirac meaning ( hamiltonian- accompanying) is the Hilbert-space self-adjoint 'canonical-conjugate' of a 'Dirac coordinate'; Riemann meaning is an algebra member of a geometrical Lie group. For the physics-employed (6-parameter) Euclid-geometrical group the two meanings coincide; for the here-employed (6-parameter) geometrical SL (2, c), they do not-due to Riemannian curvature of Milne's cosmologically-geometrical unbounded hyperbolic 'base' 3-space. A Lie-group contraction as universe age passes to infinity relates cosmological (Milne-Riemann) to physical (Euclidian) geometrical groups. But present universe age, although huge, is finite-our universe's present character being, still, far from that of its distant future. 'Age' of any spacetime location- not Hubble's photon-redshift-based age, although roughly-relatable thereto via the local-rapidity detected in cosmic background radiation (CBR)-is here (following Milne's thinking) defined to be the SL (2, c)-invariant 'Minkowski distance'- not a geometric distance-from the light-cone vertex. Common- age spatial locations occupy a hyperbolic 'base' 3-space with curved Riemann geodesics. This curvature is proportional to the inverse of (positive, cosmological) universe age-which here will be denoted by the symbol τ. According to this paper, universe- birth-age, τ 0 , was G

The objective is to provide the foundation for a quantum mechanics that is rooted exclusively in quantum-mechanical concepts, with all classical features, including the three-dimensional spatial continuum, emerging dynamically.

The correlated "opposite-parity" pair of complex 3-vectors defines a fluctuating spin-correlated lightlike ``internal velocity" as well as an independent "external rapidity". Extension from fermions to vector bosons of the velocity-fluctuation ("zitterbewegung") interpretation of rest mass weakens theoretical motivation for elementary scalar bosons.

It is shown that an experimental comparison of the deuteron and proton cross sections can be used to determine the nucleon spin flip probability.

Examples are given to demonstrate that a single pair of complex poles is capable of representing even the lowest inelastic thresholds in both total and singleparticle inclusive cross sections. The Regge mechanism that allows the position of a threshold to depend sensibly on the masses of incoming and outgoing particles is elucidated.

The Deck model is thereby interpreted as predicting the existence of the A1, rather than as undermining experimental evidence for this resonance. It is shown in general that Dolen-Horn-Schmid duality permits a vast simplification in the calculation of multiple-production processes.

It is shown that a single pair of such poles, the imaginary part of whose position in the complex J plane is of the order +/- 1, can qualitatively explain various anomalies that have been observed in high energy phenomena. Predictions are made for future measurements.
