Tasting flavoured Majorana dark matter

open access: yesJournal of High Energy Physics, 2022
We study a simplified model of flavoured Majorana dark matter in the Dark Minimal Flavour Violation framework. The model extends the Standard Model by a dark matter flavour triplet and a scalar mediator, through which the new dark fermions couple to ...

Flavour physics and CP violation [PDF]

open access: yes, 2010
It is well known that the study of flavour physics and CP violation is very important to critically test the Standard Model and to look for possible signature of new physics beyond it.

Study of singly heavy baryon lifetimes

open access: yesJournal of High Energy Physics, 2023
We study the inclusive decay widths of singly heavy baryons with the improved bag model in which the unwanted center-of-mass motion is removed. Additional insight is gained by comparing the charmed and bottom baryons. We discuss the running of the baryon

Measurement of CP asymmetries in D s + → η π + $$ {D}_{(s)}^{+}\to \eta {\pi}^{+} $$ and D s + → η ′ π + $$ {D}_{(s)}^{+}\to {\eta}^{\prime }{\pi}^{+} $$ decays

open access: yesJournal of High Energy Physics, 2023
Searches for CP violation in the decays D s + → η π + $$ {D}_{(s)}^{+}\to \eta {\pi}^{+} $$ and D s + → η ′ π + $$ {D}_{(s)}^{+}\to {\eta}^{\prime }{\pi}^{+} $$ are performed using pp collision data corresponding to 6 fb −1 of integrated luminosity ...

Mixing and CP violation in the beauty and charm sectors at LHCb

open access: yesEPJ Web of Conferences, 2014
The LHCb detector is a dedicated heavy flavour experiment operating at the Large Hadron Collider designed to pursue an extensive study of CP violation in the beauty and charm sectors.

Search for CP violation in D s + $$ {D}_{(s)}^{+} $$ → K − K + K + decays

open access: yesJournal of High Energy Physics, 2023
A search for direct CP violation in the Cabibbo-suppressed decay D s + $$ {D}_s^{+} $$ → K − K + K + and in the doubly Cabibbo-suppressed decay D + → K − K + K + is reported.

On CP Asymmetries in Two-, Three- and Four-Body D Decays [PDF]

open access: yes, 2012
Indirect and direct CP violations have been established in K_L and B_d decays. They have been found in two-body decay channels -- with the exception of K_L to pi^+ pi^- e^+ e^- transitions.

The charm of 331

open access: yesJournal of High Energy Physics, 2021
We perform a detailed analysis of flavour changing neutral current processes in the charm sector in the context of 331 models. As pointed out recently, in the case of Z′ contributions in these models there are no new free parameters beyond those already ...

CP-violation for Electroweak Baryogenesis from Dynamical CKM Matrix [PDF]

open access: yes, 2017
We show that the CKM matrix can be the source of CP violation for electroweak baryogenesis if Yukawa couplings vary at the same time as the Higgs acquires its vacuum expectation value.
