Measurements of CP asymmetries in hadron decays integrated over time provide access to direct CP violation, which arises from differences between the amplitudes of CP-conjugate decay processes. These proceedings present an overview of…
A possible supplementary mechanism of CP-violation to the Kobayashi-Maskawa theory is considered in the context of dynamical symmetry breaking.
We study spontaneous CP violation as a solution to the strong CP problem in left-right symmetric theories. The discrete CP symmetry is broken by a complex vacuum expectation value of a right-handed Higgs doublet. Heavy vectorlike down-type…

Symmetry-breaking phase transitions are ubiquitous in condensed matter systems and in quantum field theories. There is also good reason to believe that they feature in the very early history of the Universe. At many such transitions…
