SO(10) × S4 grand unified theory of flavour and leptogenesis
Journal of High Energy Physics, 2017 Abstract We propose a Grand Unified Theory of Flavour, based on SO(10) together with a non-Abelian discrete group S4, under which the unified three quark and lepton 16-plets are unified into a single triplet 3′. The model involves a further discrete group ℤ 4 R

From Nonstandard Analysis to Various Flavours of Computability Theory [PDF]
, 2017 As suggested by the title, it has recently become clear that theorems of Nonstandard Analysis (NSA) give rise to theorems in computability theory (no longer involving NSA). Now, the aforementioned discipline divides into classical and higher-order computability theory, where the former (resp.

NNLO positivity bounds on chiral perturbation theory for a general number of flavours
Journal of High Energy Physics, 2022 Abstract We present positivity bounds, derived from the principles of analyticity, unitarity and crossing symmetry, that constrain the low-energy constants of chiral perturbation theory. Bounds are produced for 2, 3 or more flavours in meson-meson scattering with equal meson masses, up to and including next-to-next-to-leading order

Yukawa textures from non-invertible symmetries
Journal of High Energy PhysicsPhenomenological aspects of non-invertible symmetries, in particular the flavor structure of quarks and leptons, are studied. We start with a ℤ M discrete symmetry and gauge ℤ2 so as to obtain a non-invertible symmetry. We study which Yukawa textures can

Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction We developed MedSupport, a multilevel medication adherence intervention designed to address root barriers to medication adherence. This study sought to explore the feasibility and acceptability of the MedSupport intervention strategies to support a future full‐scale randomized controlled trial.

More about quark Yukawa textures from selection rules without group actions
Journal of High Energy PhysicsWe study the coupling selection rules associated with non-group symmetries, i.e., ℤ2 gauging of ℤ M symmetries. We clarify which Yukawa textures can be derived by our selection rules for M = 3, 4, and 5, and obtain various textures including the nearest ...

Modular flavour symmetry and orbifolds
Journal of High Energy Physics, 2023 We develop a bottom-up approach to flavour models which combine modular symmetry with orbifold constructions. We first consider a 6d orbifold 𝕋2 /ℤ N , with a single torus defined by one complex coordinate z and a single modulus field τ, playing the role

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Despite their increased risk for functional impairment resulting from cancer and its treatments, few adolescents and young adults (AYAs) with a hematological malignancy receive the recommended or therapeutic dose of exercise per week during inpatient hospitalizations.

Lepton mass textures from non-invertible multiplication rules
Journal of High Energy PhysicsWe study the lepton mass textures, which are derived by ℤ 2 gauging of ℤ M symmetries. We can obtain various textures for the Yukawa couplings in the charged lepton sector, but the patterns of neutrino mass matrices are limited. All the obtained textures

A 4 modular flavour model of quark mass hierarchies close to the fixed point τ = i∞
Journal of High Energy Physics, 2023 We study the possibility to generate the quark mass hierarchies as well as the CKM quark mixing and CP violation without fine-tuning in a quark flavour model with modular A 4 symmetry.
