Adding flavour to twistor strings [PDF]
, 2007 Twistor string theory is known to describe a wide variety of field theories at tree--level and has proved extremely useful in making substantial progress in perturbative gauge theory.

Exotic particles below the TeV from low scale flavour theories [PDF]
, 2010 A flavour gauge theory is observable only if the symmetry is broken at relatively low energies. The intrinsic parity-violation of the fermion representations in a flavour theory describing quark, lepton and higgsino masses and mixings generically ...

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

FEBS Open Bio, EarlyView.Bioscience students were asked for their opinions on the value and teaching of skills. 204 responded that teamwork, time management and study skills are necessary to reach University, that scientific writing, research, laboratory and presentation skills are taught effectively during their studies, while other skills are gained inherently through study ...

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 ...

Minimal flavour violation: an effective field theory approach [PDF]
Nuclear Physics B, 2002 We present a general analysis of extensions of the Standard Model which satisfy the criterion of Minimal Flavour Violation (MFV). We define this general framework by constructing a low-energy effective theory containing the Standard Model fields, with one or two Higgs doublets and, as the only source of SU(3)^5 flavour symmetry breaking, the background

Pathways and pitfalls: a qualitative study of student experiences in biomedical science education
FEBS Open Bio, EarlyView.Biomedical science students from underrepresented backgrounds face barriers including financial strain, disrupted laboratory access and cultural exclusion. Peer networks provide vital support when institutional systems are difficult to navigate. To create inclusive learning environments and achieve academic success, educators should blend active, hands‐

Neutrino masses and lepton flavour violating phenomena in the MSSM [PDF]
, 2007 The most general supersymmetric model with minimal particle content and an additional discrete Ƶ(_3) symmetry, which allows lepton number violating terms, is considered. In this model, we calculate at the level of one-loop the resulting Majorana neutrino
