Renormalisation group analysis of scalar Leptoquark couplings addressing flavour anomalies: emergence of lepton-flavour universality

open access: yesJournal of High Energy Physics, 2023
Leptoquarks with masses between 2 TeV and 50 TeV are commonly invoked to explain deviations between data and Standard-Model (SM) predictions of several observables in the decays b → cτ ν ¯ $$ b\to c\tau \overline{\nu} $$ and b → sℓ + ℓ − with ℓ = e, μ ...

Dispersive analysis of B → K (*) and B s → ϕ form factors

open access: yesJournal of High Energy Physics, 2023
We propose a stronger formulation of the dispersive (or unitarity) bounds à la Boyd-Grinstein-Lebed (BGL), which are commonly applied in analyses of the hadronic form factors for B decays.

On the impact of meson mixing on B s → ϕee angular observables at low q 2

open access: yesJournal of High Energy Physics, 2023
Decays based on the b → sγ transition are expected to yield left-handed photons in the Standard Model, but could be particularly sensitive to New Physics contributions modifying the short-distance Wilson coefficients C $$ \mathcal{C} $$ 7 and C ...

Searches for B0(s)→J/ψppˉ and B+→J/ψppˉπ+ decays [PDF]

open access: yes, 2013
The results of searches for B0(s)→J/ψ pp¯ and B + → J/ψ p p¯ π+ decays are reported. The analysis is based on a data sample, corresponding to an integrated luminosity of 1.0 fb−1 of pp collisions, collected with the LHCb detector.

Heavy quark physics on the lattice with improved nonrelativistic actions

open access: yes, 2010
Hadrons containing heavy quarks, in particular b quarks, play an important role in high energy physics. Measurements of their electroweak interactions are used to test the Standard Model and search for new physics.

Rare kaon decays

open access: yesComptes Rendus. Physique, 2020
The article reviews the status of rare K decay physics. The explored area covers a broad program, ranging from precise tests of flavour theory and CP-violation to the searches for explicit violations of the standard model and the study of strong ...

FCNC B and K meson decays with light bosonic Dark Matter

open access: yesJournal of High Energy Physics, 2023
We consider decays of B and K mesons into a pseudo-scalar or vector meson plus missing energy. Within the SM, these modes originate from flavor changing neutral current (FCNC) processes with two neutrinos in the final state. In this paper we consider the

Rare Muon Decays

open access: yesActa Physica Polonica B, 2013
In this paper, we present a short review of searches for charged lepton flavour violation on the example of rare muon decays. We discuss the evaluation of electron spectrum for muon decay in orbit which is a background process for conversion experiments.
