Chiral symmetry conservation principle
Chirality, 2021AbstractWe show a chiral symmetry conservation principle based on chemical kinetics using stochastic results. Suppose the chiral symmetry conservation is evoked, and our universe can be considered globally asymmetric. In that case, there are at least two mirrored asymmetric universes if all the chiral properties are strongly correlated. However, if the

Abstract By comparing these results with the eqns (5.54) and (5.58) obtained in Part (a), we note that these charge-field commutators just yield the variation of the field under the isospin transformation with some parameter α i-:

Abstract This chapter introduces chiral symmetry, the extra symmetry that QCD acquires when the masses of quarks are set to zero. It introduces the concept of spontaneous symmetry breaking and explains the spontaneous breaking of chiral symmetry in QCD.

Abstract Recent developments related to chiral symmetry and its explicit breaking by quark masses are summarized. We discuss the status of the pion-nucleon sigma term and questions of threshold π° photoproduction.

Spontaneous Breakings of Chiral Symmetries
Physical Review D, 1970We analyze in detail the spontaneous breakings of chiral $\mathrm{SU}(3)\ensuremath{\bigotimes}\mathrm{SU}(3)$ and $\mathrm{SU}(2)\ensuremath{\bigotimes}\mathrm{SU}(2)$. We determine the directions along which the two groups may break spontaneously.

Abstract A generalized chiral symmetry is shown to exist for all massless particles and for some descriptions of massive particle theories. In addition, symmetries analogous to the generalized chiral symmetry are described, especially for spin one-half.

We have constructed a chiral-symmetry model in which the vector mesons (which are not introduced by means of the Yang-Mills technique) are described in terms of an antisymmetric second-rank tensor ${T}_{\ensuremath{\mu}\ensuremath{\nu}}$. As a result, the interaction Hamiltonian in the interaction representation contains additional contact-type terms ...
