Plan B: new Z′ models for b → sℓ + ℓ − anomalies
Journal of High Energy Physics, 2023 Measurements of b → sμ + μ − transitions indicate that there may be a new physics field coupling to di-muon pairs associated with the b to s flavour transition.

Monodromy defects in free field theories [PDF]
Journal of High Energy Physics, 2021 We study co-dimension two monodromy defects in theories of conformally coupled scalars and free Dirac fermions in arbitrary d dimensions. We characterise this family of conformal defects by computing the one-point functions of the stress-tensor and ...

Journal of High Energy Physics, 2023 We present the first complete model of the Littlest Modular Seesaw, based on two right-handed neutrinos, within the framework of multiple modular symmetries, justifying the use of multiple moduli fields which take their values at 3 specific stabilizers ...

Generalised CP symmetry in modular-invariant models of flavour [PDF]
Journal of High Energy Physics, 2019 The formalism of combined finite modular and generalised CP (gCP) sym-metries for theories of flavour is developed. The corresponding consistency conditions for the two symmetry transformations acting on the modulus τ and on the matter fields are derived.

Double cover of modular S4 for flavour model building [PDF]
Nuclear Physics B, 2020 We develop the formalism of the finite modular group $\Gamma'_4 \equiv S'_4$, a double cover of the modular permutation group $\Gamma_4 \simeq S_4$, for theories of flavour.

Fermion masses, critical behavior and universality
Journal of High Energy Physics, 2023 We look for signals of critical behavior in the Yukawa sector. By reviewing a set of models for the fermion masses, we select those where a symmetry-breaking order parameter sits at a transition point between a disordered phase and an ordered one.

Lepton number and flavour violation in TeV-scale left-right symmetric theories with large left-right mixing [PDF]
Journal of High Energy Physics, 2013 A bstractThe various diagrams leading to neutrinoless double beta decay in the left-right symmetric model have different relative magnitudes, depending on the scale of new physics.

Group Processes & Intergroup Relations, 2021 Conspiracy theories started to appear on social media immediately after the first news about COVID-19. Is the virus a hoax? Is it a bioweapon designed in a Chinese laboratory?

∆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

Exploring the flavor structure of quarks and leptons with reinforcement learning
Journal of High Energy Physics, 2023 We propose a method to explore the flavor structure of quarks and leptons with reinforcement learning. As a concrete model, we utilize a basic value-based algorithm for models with U(1) flavor symmetry.
