Current Algebra ofSU(6)Wand Nonleptonic Hyperon Decays

Theory of Weak Hypernuclear Decay

“…where J i µj = (V + A) i µj is the weak hadronic current with SU(3) indices i,j, G v ≈ 10 −5 m −2 p is the conventional weak coupling constant, and θ c is the Cabibbo angle. Now following the procedure of Balachandran et al [19] we express the vector and axial currents in terms of SU(6) w currents P,Q,R,S…”

“…[17] This is sufficient for a full treatment of weak nonleptonic vertices. The first applications to weak phenomenology were those of McKellar and Pick [18] and of Balachandran et al, [19] while a comprehensive SU (6) w treatment of nuclear parity violation was presented in ref. 10.…”

Quark and pole models of nonleptonic decays of charmed baryons

“…The approach of this paper constitutes an application to the charmed baryon sector of the quark-model technique used in the description of the ∆S = 1 hyperon decays in refs. [8,9,13]. The main idea of these papers was to separate from the dynamics the quark-model-based spin-flavour symmetry relations between the amplitudes.…”

Analysis of the nonleptonic two-body decays of the $Λ$ hyperon

“…Since end of 1960-s two-body nonleptonic decays of the Λ hyperon have been studied in the literature using different approaches. One of the first attempts to the Λ and other hyperons have been done by using effective weak Hamiltonians and methods of current algebra, dispersion relations, and vector dominance [15][16][17][18][19][20][21][22][23][24]. In Ref.…”
