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.

Flavour physics in the LHC era

, 2014
These lectures give a topical review of heavy flavour physics, in particular \CP violation and rare decays, from an experimental point of view. They describe the ongoing motivation to study heavy flavour physics in the LHC era, the current status of the ...

Hadronization -- the Unsung Hero rather than the Alleged Villain in the Tale of CP Violation

, 2005
The novel successes scored by the Standard Model of High Energy Physics in the last few years concerning heavy flavour dynamics do not weaken the case for `New Physics' around the TeV scale. They do suggest however that one cannot {\em count} on that New

Conclusions from CDF Results on CP Violation in D^0 \to \pi^+\pi^-, K^+K^- and Future Tasks

, 2011
Within the Standard Model (SM) one predicts both direct and indirect CP violation in D^0 \to \pi^+\pi^-, K^+K^- transitions, although the effects are tiny: Indirect CP asymmetry cannot exceed O(10^{-4}), probably even O(10^{-5}); direct effects are ...

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.

Indirect CP violation results and HFAG averages

, 2013
The current status of the search for indirect CP violation in the neutral D meson system at the B-factories and at LHCb is reported. The indirect CP asymmetry search is performed by the measurement of the proper-time asymmetry ($A_{\Gamma}$) in decays of

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.

Manifestations of Warped Extra Dimension in Rare Charm Decays and Asymmetries

, 2014
We study the effects of models with a warped extra dimension on rare charm decays. While the new degrees of freedom in these models are bounded above a few TeV, they can leave signatures in rare charm decays with their tiny Standard Model background.

Relating LHC event rates to supersymmetric Grand Unified Theories containing $SU(5)$

, 2015
We elaborate on a recently found $SU(5)$ relation confined to the up-(s)quark flavour space, that remains immune to large quantum corrections up to the TeV scale.

Measurements of CP Violation and Mixing in Charm Decays at LHCb

, 2014
During run I, the LHCb experiment at the LHC, CERN, collected 1.0 fb$^{-1}$ of pp collisions at $\sqrt{s} = 7$ TeV and 2.0 fb$^{-1}$ at $\sqrt{s} = 8$ TeV, yielding the world's largest sample of decays of charmed hadrons.
