CPT-odd Leptogenesis
Pavel A. Bolokhov, Maxim Pospelov
We calculate the baryon asymmetry of the Universe resulting from the combination of higher-dimensional Lorentz-noninvariant CPT-odd operators and dimension five operators that indu…
Electric dipole moment constraints on minimal electroweak baryogenesis
Stephan J. Huber, Maxim Pospelov, Adam Ritz
We study the simplest generic extension of the Standard Model which allows for conventional electroweak baryogenesis, through the addition of dimension six operators in the Higgs s…
Electric Dipole Moments as Probes of CPT Invariance
Pavel Bolokhov, Maxim Pospelov, Michael Romalis
Electric dipole moments (EDMs) of elementary particles and atoms probe violations of T and P symmetries and consequently of CP if CPT is an exact symmetry. We point out that EDMs c…
Sensitivity to new supersymmetric thresholds through flavour and CP violating physics
Maxim Pospelov, Adam Ritz, Yudi Santoso
Treating the MSSM as an effective theory below a threshold scale Lambda, we study the consequences of having dimension-five operators in the superpotential for flavour and CP-viola…
Particle physics catalysis of thermal Big Bang Nucleosynthesis
Maxim Pospelov
We point out that the existence of metastable, tau > 10^3 s, negatively charged electroweak-scale particles (X^-) alters the predictions for lithium and other primordial elemental…
