Results and prospects for Charm Physics at LHCb

open access: yes, 2011
Precision measurements in charm physics offer a window into a unique sector of potential New Physics interactions. LHCb is well equipped to take advantage of the enormous production cross-section of charm mesons in $pp$ collisions at $\sqrt{s}=7$ TeV ...

Searches for CP violation in two-body charm decays

open access: yes, 2015
The LHCb experiment recorded data corresponding to an integrated luminosity of 3.0 $fb^{-1}$ during its first run of data taking. These data yield the largest samples of charmed hadrons in the world and are used to search for CP violation in the $D^0 ...

CP Violation in D0 - anti-D0 Oscillations: General Considerations and Applications to the Littlest Higgs Model with T-Parity

open access: yes, 2009
The observed D0 - anti-D0 oscillations provide a new stage in our search for New Physics in heavy flavour dynamics. The theoretical verdict on the observed values of x_D and y_D remains ambiguous: while they could be totally generated by Standard Model ...

New Physics Signatures in Kaon Decays [PDF]

open access: yes, 2013
Kaon physics provides a unique opportunity to identify new flavour and CP violating interactions beyond the Standard Model (SM). In the SM, implied by the hierarchical structure of the CKM matrix and the GIM mechanism, flavour changing neutral current ...

The neutron EDM vs up and charm flavour violation

open access: yes, 2014
We derive a strong bound on the chromo-electric dipole moment of the charm quark, and we quantify its impact on models that allow for a sizeable flavour violation in the up quark sector. In particular we show how the constraints coming from the charm and up CEDMs limit the size of new physics contributions to direct flavour violation in D meson decays.

Systematics of U-spin sum rules for systems with direct sums

open access: yesJournal of High Energy Physics
A rich mathematical structure underlying flavor sum rules has been discovered recently. In this work, we extend these findings to systems with a direct sum of representations. We prove several results for the general case.

A search for time-integrated CP violation in D0 → h−h+ decays

open access: yesEPJ Web of Conferences, 2012
The preliminary results of a search for time-integrated CP violation in D0 → h−h+ (h = K, π) decays performed with 0.6 fb− of data collected by LHCb in 2011 are presented. The flavour of the charm meson is determined by the charge of the slow pion in the

Measurement of CP asymmetry in D0→K−K+ decays

open access: yesPhysics Letters B, 2017
A measurement of the time-integrated CP asymmetry in the Cabibbo-suppressed decay D0→K−K+ is performed using pp collision data, corresponding to an integrated luminosity of 3 fb−1, collected with the LHCb detector at centre-of-mass energies of 7 and 8 ...

CP violation in charm and beauty decays at LHCb

open access: yes, 2012
LHCb is a dedicated heavy flavour physics precision experiment at the LHC searching for New Physics (NP) beyond the Standard Model (SM) through the study of very rare decays of beauty and charm-flavoured hadrons and precision measurements of CP-violating

Charmed Λ c + $$ {\Lambda}_c^{+} $$ baryon decays into light scalar mesons in the topological SU(3) f framework

open access: yesJournal of High Energy Physics
Using the topological-diagram approach based on SU(3) flavor symmetry, we investigate two-body Λ c + → B S $$ {\Lambda}_c^{+}\to \textbf{B}S $$ decays, where B denotes the final-state baryon and S refers to a light scalar meson, such as f 0/f 0(980), a 0/
