Flavour-kinematics duality for Goldstone modes [PDF]
Journal of High Energy Physics, 2022 Three scalar effective field theories have special properties in terms of non-linear symmetries, soft limits and on-shell constructability that arise from their Goldstone nature: the non-linear σ-model, multi-DBI theory and the special Galileon.

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.

Journal of High Energy Physics, 2022 We study the flavor structure of the lepton and baryon number-conserving dimension-6 operators in the Standard Model effective field theory (SMEFT). Building on the work of [1], we define several well-motivated flavor symmetries and symmetry-breaking ...

The European Physical Journal Plus, 2023 Einstein–Gauss–Bonnet gravity in five dimensions is applied to compact stellar objects, in particular to quark stars obeying a colour-flavour-locked equation of state. Matter under such extreme conditions welcomes the use of higher-order gravity theories

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.

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?

Two string theory flavours of generalised Eisenstein series
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.

Modular flavor symmetry and vector-valued modular forms
Journal of High Energy Physics, 2022 We revisit the modular flavor symmetry from a more general perspective. The scalar modular forms of principal congruence subgroups are extended to the vector-valued modular forms, then we have more possible finite modular groups including Γ N and Γ N ′ $$

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 ...
