چکیده

Mev. The quantity b& has been unobserved in lower energy m experiments partly because the data were analyzed under the assumption that it is zero. On the other hand, (3.7) predicts, even with an f'as low as 0.08, a value of —0.166&0.014 for br+2ats+arr. This would seem to imply, if the dispersion relations are correct, that one or two of the quantities b1, u13, and a11, are much larger than has so far been observed. To estimate what values b1, a13, and a11 should have to be consistent with the dispersion relations, let us take f'=0.10. Then bt+2ars+ atr = —0.254, f'=0.10. (3.9)

Remarks on Possible Noninvariance under Time Reversal and Charge Conjugation

'N a recent paper' the question has been raised as ~ to whether the weak interactions are invariant under a space inversion. It was also pointed out there that similar to the situation for space inversion there exists at present no experimental proof that weak interactions are invariant under charge conjugation. Consequently the absolute invariance under charge conjugation is also an open quest...

Duality Theory of Weak Interactions

The main objectives of this article are 1) to derive a field theory of weak interactions, 2) to study the duality of weak interactions, and 3) to derive the long overdue weak potential and force formula. The new field equations for weak interactions is derived by applying the principle of interaction dynamics (PID) and the principle of representation invariance (PRI) to a standard SU(2) gauge a...

Time-reversal and parity conservation for gravitating quarks

The complex mass term of a quark does not violate time-reversal or parity in gravitational interactions, in spite of an axial anomaly. Time-reversal is known to be violated in the weak interactions. Mass terms q̄LMqR + ̄̃qLM̃q̃R+hc are generated for quarks q having charge + 2 3 and quarks q̃ having charge − 1 3 in the shape of complex matrices M, M̃ from electroweak symmetry breaking. On diagonalizati...

سهم برهمکنش‌های CSB در اختلاف انرژی بستگی هسته‌های آینه‌ای

  Nolen-Schiffer Anomaly in mirror nuclei due to the NN interactions with isospin mixing between T=0 and T=1 mesons of the same spin and parity are investigated. With the computation of coulomb energy along with the charge symmetry breaking (CSB) effects provide a reasonably accurate description of binding energy differences between  39ca- 39k- , 41cs- 41ca mirror nuclei.

Subgroup Alignment in Hypercolor Theories

To analyze the physical consequences of a dynamically broken theory of the weak interactions, we must know how the weak gauge group is aligned in an approximate flavor-symmetry group. For a large class of models, spectral-function sum rules enable us to determine this alignment explicitly. We work out the pattern of the electroweak symmetry breakdown for several sample models. Critical values o...

Electroweak Quark–lepton Symmetry and Weak Topological-charge Confinement in the Standard Model with Dirac Neutrinos

The standard electroweak model with Dirac neutrinos is extended by way of the principles of electroweak quark–lepton symmetry and weak topological-charge confinement to account for quark–lepton charge relations which, if not accidental, are indicative of charge structures. A mixing in quarks and leptons of underlying integer local charges with integer weak topological charges associated with an...
