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

Journal 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.

Search for Lepton Flavour Violation in four-body charm decays at LHCb [PDF]

This dissertation presents a search for physics beyond the standard model by the study of lepton flavour violation in four-body charm decays. A search for the decays $D^0 \to \pi^- \pi^+ \mu^\pm e^\mp$ , $D^0 \to K^- \pi^+ \mu^\pm e^\mp$ and $D^0 \to K^- K^+ \mu^\pm e^\mp$ using data collected by the LHCb experiment is performed. These decays provide a

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

Journal 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/

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

EPJ 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

Physics 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 ...

Model-independent bounds on light pseudoscalars from rare B-meson decays

Physics Letters B, 2019
New light pseudoscalars, such as axion-like particles, appear in many well-motivated extensions of the Standard Model and provide an exciting target for present and future experiments.

D → Pℓ + ℓ − decays assisted by QCD light-cone sum rules

Journal of High Energy Physics
We suggest a new method to analyse the rare D (s) → Pℓ + ℓ − decays (P = π, K), combining QCD light-cone sum rules (LCSR) with hadronic dispersion relations.

Patterns of New Physics in b → sℓ+ℓ− transitions in the light of recent data

Journal of High Energy Physics, 2018
In the Standard Model (SM), the rare transitions where a bottom quark decays into a strange quark and a pair of light leptons exhibit a potential sensitivity to physics beyond the SM.
