A Master Formula for Chiral Symmetry Breaking
We derive a master formula for chiral SU(2)×SU(2) breaking, based on the VeltmanBell equations and the Peierls-Dyson relation. Our approach does not rely on the use of the soft pion limit or an expansion around the chiral limit, and yields exact results for on-shell pions. Threshold theorems for πN → πN , γN → πN , πN → ππN , γN → γπN , γN → ππN and πN → πγN are recovered, and corrections to th...
متن کاملTHE FRANK KINETIC MODEL FOR SPONTANEOUS CHIRAL SYMMETRY BREAKING WITH VARIABLE CONCENTRATION OF THE ACHIRAL SUBSTRATE
This paper considers the possibility of spontaneous transition of aracemic mixture (composed of equal amounts of two enantiomeric species, say L and D) into a monochiral state (in which only one enantiomer, say L, is present). Transitions of this kind have been recently experimentally observed. A plausible approach to this phenomenon is a model put forward by Frank, based on simple laws of ...

متن کاملChiral Symmetry Breaking by Instantons
Instantons are certain configurations of the Yang–Mills potentials Aμ(x) satisfying the equations of motion D μ F b μν = 0 in euclidean space, i.e. in imaginary time. The solution has been found by Belavin, Polyakov, Schwartz and Tiupkin in 1975 [1]; the name ”instanton” has been suggested by ’t Hooft in 1976 [2], who also made a major contribution to the investigation of the instantons propert...
