Higgs boson decay to charm pair at full one-loop level in the MSSM with flavour violation

, 2014
We study the decay of the lightest neutral Higgs boson to a charm quark pair at full one-loop level in the MSSM with non-minimal quark flavour violation (QFV). In the numerical analysis we consider mixing between the second and the third squark generation and all relevant constraints from B meson data are taken into account.

ΔA CP within the Standard Model and beyond

Journal of High Energy Physics, 2019
In light of the recent LHCb observation of CP violation in the charm sector, we review standard model (SM) predictions in the charm sector and in particular for ΔA CP.

The Impact of a 4th Generation on Mixing and CP Violation in the Charm System [PDF]

, 2010
We study D0-D0 mixing in the presence of a fourth generation of quarks. In particular, we calculate the size of the allowed CP violation which is found at the observable level well beyond anything possible with CKM dynamics. We calculate the semileptonic

What Next in Flavour Physics and CP Violation? [PDF]

, 2002
The future of flavour physics and CP violation in the quark, lepton and Higgs sectors are discussed, particularly from the viewpoint of physics beyond the Standard Model, such as supersymmetry. Current issues in B to pi^+ pi^-, phi K_s and D^*+ D^*-, B_s

Introduction to Charm Physics

, 2015
This paper gives an overview of charm physics. It is a lecture write-up aimed at students with a minimum of prior knowledge in particle physics, but at the same time provides a state-of-the art review of the field.

Anatomy of non-leptonic two-body decays of charmed mesons into final states with η′

Journal of High Energy Physics
We show that D → Pη′ decay amplitudes, where P = K, π, η, cannot be simply related to their D → Pη counterparts with a single η 0–η 8 mixing angle. We propose a novel, consistent treatment of η 0–η 8 mixing for application in D → Pη and D → Pη′ decays ...

Lessons from charm dynamics [PDF]

, 2013
We shall proceed to discuss the significance of charm dynamics in an era when the Standard Model is well established in its degrees of freedom but little understood in quite a few of its different parts.

Charmed baryon decays: SU(3) F breaking and CP violation

Journal of High Energy Physics
We present a comprehensive study of anti-triplet charmed baryon decays into octet baryons and pseudoscalar mesons using the SU(3) F flavor symmetry framework.

The impact of SuperB on flavour physics [PDF]

, 2011
This report provides a succinct summary of the physics programme of SuperB, and describes that potential in the context of experiments making measurements in flavour physics over the next 10 to 20 years.

Final-state rescattering mechanism of charmed baryon decays

Journal of High Energy Physics
The dynamical studies on the non-leptonic weak decays of charmed baryons are always challenging, due to the large non-perturbative contributions at the charm scale. In this work, we develop the final-state rescattering mechanism to study the two-body non-
