Exploring CP violation in the MSSM. [PDF]

Eur Phys J C Part Fields, 2015
We explore the prospects for observing CP violation in the minimal supersymmetric extension of the Standard Model (MSSM) with six CP-violating parameters, three gaugino mass phases and three phases in trilinear soft supersymmetry-breaking parameters, using the CPsuperH code combined with a geometric approach to maximize CP-violating observables subject

Double-mixing CP violation in B decays

European Physical Journal C: Particles and Fields
We study a long-overlooked CP violation observable, termed double-mixing CP violation, which arises from the interference between two neutral meson oscillating paths involved in a decay chain.

On the determination of leptonic CP violation and neutrino mass ordering in presence of non-standard interactions: present status

Journal of High Energy Physics, 2019
We perform a global analysis of neutrino data in the framework of three massive neutrinos with non-standard neutrino interactions which affect their evolution in the matter background. We focus on the effect of NSI in the present observables sensitive to

CP violation in loop-induced diboson production

Journal of High Energy Physics
We consider the impact of CP-violating Higgs and top interactions on diboson production from gluon fusion within the Standard Model Effective Field Theory framework.

Cp violation analysis of $$D^0\rightarrow M^0 K \rightarrow M^0(\pi ^\pm \ell ^\mp \nu )$$ D 0 → M 0 K → M 0 ( π ± ℓ ∓ ν )

European Physical Journal C: Particles and Fields
CP violation in the charm sector is highly sensitive to new physics due to its small predicted value within the standard model. By this work, we investigated the CP violation in the cascade decay process $$D^0(t_1) \rightarrow \pi ^0 K(t_2) \rightarrow ...

CP violation in H ± → W ± Z: a physical approach for the 2HDM

Journal of High Energy Physics
We investigate CP violation in the process H ± → W ± Z within the framework of the two-Higgs-Doublet model (2HDM). Amplitudes are expressed transparently in terms of physical couplings.

A D 5 model of quarks with explicit CP violation

Journal of High Energy Physics
The hierarchy of fermion masses and mixings lacks a self-consistent theoretical explanation at the dynamical or symmetry level, and the origin of CP violation remains unclear. These two issues have long been major challenges in particle physics.

CP violation in neutral kaon mixing in D 0 → K S K S

Journal of High Energy Physics
We study CP violation induced by neutral kaon mixing in a CP(D 0 → K S K S ). We show that the contribution from neutral kaon mixing arises only in connection with second-order weak interactions in D decays.

Loop induced H ± W ∓ Z vertices in the general two Higgs doublet model with CP violation

Journal of High Energy Physics
Understanding symmetry of extended Higgs models helps to construct the theory beyond the standard model and gives important insights for testing these models by experiments.
