Heavy vector-like quarks decaying to exotic scalars: a case study with triplets

Journal of High Energy Physics
We investigate the pair production of a vector-like quark triplet with hypercharge 5/3 decaying into top quark and a complex scalar triplet with hypercharge 1 at the LHC.

R K * $$ {R}_{K^{\left(*\right)}} $$ with leptoquarks and the origin of Yukawa couplings

Journal of High Energy Physics, 2018
We construct a model where the Yukawa couplings of the Standard Model (SM) fermions arise from the breaking of a Z 2 symmetry and through mixing with a fourth family of vector-like fermions.

A Perspective on Interactive Theorem Provers in Physics

Advanced Science, EarlyView.
Into an interactive theorem provers (ITPs), one can write mathematical definitions, theorems and proofs, and the correctness of those results is automatically checked. This perspective goes over the best usage of ITPs within physics and motivates the open‐source community run project PhysLean, the aim of which is to be a library for digitalized physics

Type‐II Dirac Fermions in Monolayer In2O: Interplay of Magnetotransport, Spin Hall Effect, and Superconductivity

Advanced Science, EarlyView.
First‐principles calculations reveal that monolayer In2O${\rm In}_2{\rm O}$ hosts type‐II Dirac fermions near the Fermi level, which split into Weyl points under spin‐orbit coupling. The material exhibits negative and giant magnetoresistance, a pronounced spin Hall effect, and phonon‐mediated superconductivity at 1.5 K, establishing it as a unique ...

Dark top partner

Journal of High Energy Physics, 2023
Composite Higgs models with extended symmetries can feature mesonic dark matter candidates. In fundamental CHMs, the origin of dark parity can be explained in the UV theory.

Photonic‐Enabled Energy‐Efficient Transparent Neuromorphic Computing Devices: A Review

Advanced Science, EarlyView.
Transparent photonic neuromorphic computing devices merge optics and brain‐inspired computing to overcome von Neumann bottlenecks with ultrafast, low‐energy processing. By exploiting transparent oxides, 2D materials, phase‐change materials, and hybrid heterostructures, these platforms enable photonic synapses, memory, and logic for see‐through edge ...

Vector-like quark doublets, weak-basis invariants and CP violation

Journal of High Energy Physics
We study Standard Model extensions with isodoublet vector-like quarks with standard charges. Their presence induces right-handed charged and neutral currents.

Naturally light Dirac and pseudo-Dirac neutrinos from left-right symmetry

Journal of High Energy Physics, 2022
We develop a class of left-right symmetric theories based on the gauge group SU(3) c × SU(2) L × SU(2) R × U(1) with a generalized seesaw mechanism for generating the charged fermion masses.
