A bstract Parity solutions to the strong CP problem are a compelling alternative to
approaches based on Peccei-Quinn symmetry, particularly given the expected violation of …

This paper surveys recent progress in our search for an appropriate internal space algebra
for the standard model (SM) of particle physics. After a brief review of the existing …

A bstract We present an ultraviolet complete theory for the R (D*) and R (D) anomaly in
terms of a low mass W±R gauge boson of a class of left-right symmetric models. These …

We explore the possibility of resolving simultaneously the W-boson mass shift reported by
the CDF Collaboration and the apparent deviation from unitarity in the first row of the CKM …

A bstract The baryon asymmetry of the universe may be explained by rotations of the QCD
axion in field space and baryon number violating processes. We consider the minimal …

We propose theories of a complete mirror world with parity (P) solving the strong CP
problem. P exchanges the entire standard model with its mirror copy. We derive bounds on …

A bstract We study the simplest theories with exact spacetime parity that solve the strong CP
problem and successfully generate the cosmological baryon asymmetry via decays of right …

A bstract When the QCD axion is absent in full theory, the strong CP problem has to be
explained by an additional mechanism, eg, the left-right symmetry. Even though tree-level …

Parity and CP symmetries are broken in the world around us. Nonetheless, parity (or CP)
may be a gauge symmetry which is higgsed in our universe. This is assumed in many …
