摘要:
AbstractWe reconsider the problem of giving an algebraic treatment to quantum problems within the framework of ordinary quantum mechanics. After a concise review of the irreducible representations of the relevant Lie algebra, we formulate the general scheme within which all previous approaches can be easily fitted. We then show which are the explicit connexions between this general scheme and the specific approaches found in the literature. The whole paper constitutes a concise and synthetic summary of algebraic techniques in ordinary quantum mechanics.

摘要:
AbstractWe investigate various physical consequences of theories of chiral symmetry. Predictions of the symmetry are given for the meson electroproduction process at an on‐shell kinematical point where unknown contributions are minimized. Sum rules are derived for the corrections. Then we present a sum rule for the ∑ term in meson‐baryon scattering from the assumptions of Bjorken limit, precocious asymptopia, and finite‐mass dispersion relations. We use the commutation relations of the gluon model as input for a numerical evaluation. Next the explicit canonical structure of the light‐cone restriction of the commutator of the weak current with its divergence is considered in the interacting quark‐gluon model quantized in the infinite–momentum frame. The implications on neutrino scattering are analyzed.W4andW5are predicted to scale nontrivially asv−2F4(ω) andv−2F5(ω), which provides a simple test of light‐cone current algebra feasible in the near future. The ∑ term for weak currents is deduced from a causal representation near the light‐cone, and a correction is also made in theW5– sum rule obtained by naive infinite momentum techniques. As a by‐product we obtain improved derivations of
