Invariants and CP violation in the 2HDM [PDF]
Proceedings of Corfu Summer Institute 2017 "Schools and Workshops on Elementary Particle Physics and Gravity" — PoS(CORFU2017), 2018 We discuss the importance of basis invariants in the general 2HDM and how these relates to masses and couplings. We also present a simple, yet powerful technique to translate parameters of the potential into combinations of masses and couplings of the theory and apply this to CP odd invariants.

Hamiltonian Analysis of Gauged $CP^1$ Model, the Hopf term, and fractional spin [PDF]
, 1998 Recently it was shown by Cho and Kimm that the gauged $CP^1$ model, obtained by gauging the global $SU(2)$ group and adding a corresponding Chern-Simons term, has got its own soliton.

Electron EDM arising from modulus τ in the supersymmetric modular invariant flavor models
Journal of High Energy Physics, 2021 The electric dipole moment (EDM) of electron is studied in the supersymmetric A4 modular invariant theory of flavors with CP invariance. The CP symmetry of the lepton sector is broken by fixing the modulus τ.

Using time-dependent indirect CP asymmetries to measure T and CPT violation in B0–B¯0 mixing
Physics Letters B, 2018 Quantum field theory, which is the basis for all of particle physics, requires that all processes respect CPT invariance. It is therefore of paramount importance to test the validity of CPT conservation.

Theta Term in QCD sum rules at Finite Temperature and the Neutron Electric Dipole Moment [PDF]
, 2002 By using thermal QCD sum rules to investigate the $\bar{\theta}$ induced neutron electric dipole moment $d_n$, we have examined the behaviour of broken CP symmetry at finite temperature. We find that, below the critical temperature, the ratio $\mid {d_n \

Basis invariant measure of CP-violation and renormalization
Nuclear Physics B, 2015 We analyze, in the context of a simple toy model, for which renormalization schemes the CP-properties of bare Lagrangian and its finite part coincide. We show that this is the case for the minimal subtraction and on-shell schemes. The CP-properties of the theory can then be characterized by CP-odd basis invariants expressed in terms of renormalized ...

Measurement of the Higgs Boson Couplings and CP Structure Using Tau Leptons at the LHC
, 2016 Results on the $H\to\tau\tau$ measurements performed by the ATLAS and CMS collaborations with the pp collision data collected at the LHC at $\sqrt{s}=$7 and 8 TeV are presented.

Baryogenesis in a CP invariant theory [PDF]
Journal of High Energy Physics, 2015 We consider baryogenesis in a model which has a CP invariant Lagrangian, CP invariant initial conditions and does not spontaneously break CP at any of the minima. We utilize the fact that tunneling processes between CP invariant minima can break CP to implement baryogenesis.

About Mass, CP and Extra Dimensions [PDF]
, 2006 We discuss the notion of mass, mostly for fermions, and its relation to the breaking of CP invariance, the natural symmetry of gauge interactions. In a first model, we show how compactification on a Vortex in 2 extra dimensions leads to a replication of ...
