Topology and index theorem with a generalized Villain lattice action – a test in 2d
Using 2-d U(1) lattice gauge theory we study two definitions of the topological charge constructed from a generalized Villain action and analyze the implementation of the index theorem based on the overlap Dirac operator.

Superconductivity in charge Kondo systems
We present a theory of superconductivity in charge Kondo systems, materials with resonant quantum valence fluctuations, in the regime where the transition temperature is comparable to the charge Kondo resonance.

CHARGED LEPTON FLAVOR PHYSICS AND EXTRA DIMENSIONS [PDF]
We estimate the charged lepton electric dipole moments and the branching ratios of radiative lepton flavor violating decays in the framework of the two Higgs doublet model with the inclusion of two extra dimensions. Here, we consider that the new Higgs doublet is accessible to one of the extra dimensions with a Gaussian profile and the fermions are ...

Understanding charge radii with machine learning: Discovering physics expressions
We introduce a robust, interpretable machine learning (ML) framework that combines numerical regression for high-accuracy predictions with symbolic regression to uncover the underlying physics.

Probing new physics with charge asymmetries in 2 same-sign leptons plus jets final states at the LHC
We study the impact of new physics models in the charge asymmetry defined for LHC final states consisting of two same-sign leptons (2SSl, with l = e, μ) plus jets (N jets ≥ 2), with a center-of-mass energy of s $$ \sqrt{s} $$ = 13 TeV, where the main SM ...

Reflections on Physics Education and Communication with Tibetan Monastics
Physics education research, a field that is now over 100 years old, has made it clear: the key to teaching physics successfully is to prioritize getting the concepts across, and the mathematical representation (“laws”) can come later.

Discovery of the Color Degree of Freedom in Particle Physics: a Personal Perspective
I review the main features of the color charge degree of freedom in particle physics, sketch the paradox in the early quark model that led to color, give a personal perspective on the discovery of color and describe the introduction of the gauge theory ...
