Neutrino physics in TeV scale gravity theories [PDF]
Physical Review D, 2022 In this paper, the general features of the neutrino sector in TeV scale quantum gravity theories, such as ADD and Many Species Theory, is investigated. This class of theories has an inherent way to generate small neutrino masses.

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 ...

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 ...

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 ′ $$

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?

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.

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.

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.

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 ...

Portal Effective Theories. A framework for the model independent description of light hidden sector interactions [PDF]
Journal of High Energy Physics, 2021 We present a framework for the construction of portal effective theory (PETs) that couple effective field theories of the Standard Model (SM) to light hidden messenger fields.
