Effective Theories for Quark Flavour Physics [PDF]
Effective Field Theory in Particle Physics and Cosmology, 2019 The purpose of the lectures that appear within this chapter is to provide the reader with an idea of how we can probe new physics with quark flavour observables using effective theory techniques.

Flavour mixing transport theory and resonant leptogenesis [PDF]
Journal of High Energy Physics, 2021 Abstract We derive non-equilibrium quantum transport equations for flavour-mixing fermions. We develop the formalism mostly in the context of resonant leptogenesis with two mixing Majorana fermions and one lepton flavour, but our master equations are valid more generally in homogeneous and isotropic systems.

On the Normalisation of the Modular Forms in Modular Invariant Theories of Flavour [PDF]
Physics Letters B, 2023 The problem of normalisation of the modular forms in modular invariant lepton and quark flavour models is discussed. Modular invariant normalisations of the modular forms are proposed.

A note on the holography of Chern-Simons matter theories with flavour [PDF]
Journal of High Energy Physics, 2009 We study a three-dimensional = 3 U(N)k × U(N)−k Chern-Simons matter theory with flavour, corresponding to the = 6 Aharony-Bergman-Jafferis-Maldacena CSM theory coupled to 2Nf fundamental fields.

Flavour Changing at Colliders in the Effective Theory Approach [PDF]
, 2022 In this thesis we discuss the combined effects of strong and electroweak FCNC effective operators in top quark physics at the CERN LHC and lepton flavour violation at the ILC with dimension six effective operators.

∆Ms theory precision confronts flavour anomalies [PDF]
Journal of High Energy Physics, 2019 Abstract Based on recent HQET sum rule and lattice calculations we present updated Standard Model predictions for the mass differences of neutral B mesons: $$ \varDelta {M}_s^{\mathrm{SM}}=\left({18.4}_{-1.2}^{+0.7}\right){\mathrm{ps}}^{-1} $$ Δ

Two string theory flavours of generalised Eisenstein series [PDF]
Journal of High Energy Physics, 2023 Abstract Generalised Eisenstein series are non-holomorphic modular invariant functions of a complex variable, τ, subject to a particular inhomogeneous Laplace eigenvalue equation on the hyperbolic upper-half τ-plane. Two infinite classes of such functions arise quite naturally within different string theory contexts.

Introduction to Charged Lepton Flavour Violation [PDF]
, 2022 Neutrino masses provide evidence of lepton flavour violation, but no violation in the interactions among the charged leptons has been observed yet. Many models of Physics Beyond the Standard Model (BSM) predict Charged Lepton Flavour Violation (CLFV) in ...

Low-energy effective description of dark $Sp(4)$ theories [PDF]
SciPost Physics, 2022 Strongly interacting massive particles are viable dark matter candidates. We consider a dark Sp(4)Sp(4) gauge theory with N_f=2Nf=2 fermions in the pseudo-real fundamental representation and construct the chiral low-energy effective theory.
