We give an explanation of the $\mathrm{CP}$ conservation of strong interactions which includes the effects of pseudoparticles. We find it is a natural result for any theory where at least one flavor of fermion acquires its mass through a Yukawa coupling to a scalar field which has nonvanishing vacuum expectation value.

We investigate the possibility of CP symmetry violation in strong interactions, also called the strong CP problem. We show how the problem arises in the theory of quantum chromodynamics and its…

We utilize the effective field theory approach to study the properties of the axion. In particular, with s as well as u and d quarks regarded to be relatively light we derive a formula for the mass…

Interaction of axions with relativistic spinning particles

We consider a covariant phenomenological model, which describes an interaction between a pseudoscalar (axion) field and massive spinning particles. The model extends the Bagrmann-Michel-Telegdy…

We present two original derivations of the restoration of C and CP symmetry within QCD, simplest in “standalone QCD” but extendable to include conserved QED, in the limit [Formula: see text]
