Proca-Higgs balls and stars in a UV completion for Proca self-interactions [PDF]
Journal of Cosmology and Astroparticle Physics, 2023 We consider a Proca-Higgs model wherein a complex vector field gains mass via spontaneous symmetry breaking, by coupling to a real scalar field with a Higgs-type potential.

Stringent bounds on HWW and HZZ anomalous couplings with quantum tomography at the LHC
Journal of High Energy Physics, 2023 Quantum tomography provides the full reconstruction of the density matrix of a state. We use it to study the Higgs boson decay into weak gauge bosons. Anomalous couplings beyond the Standard Model can be constrained by means of observables easily defined

Active Learning in Physics: From 101, to Progress, and Perspective
Advanced Quantum Technologies, EarlyView., 2023 In this review, the concept of active learning is introduced to the physicists at the level of beginner without requirement on background in machine learning. It includes most of the latest applications of active learning in branches of physics, covering but not being limited to quantum information, high energy physics, and condensed matter physics. It

The general Two-Higgs Doublet Model in a gauge-invariant form
Journal of High Energy Physics, 2022 In the general Two-Higgs Doublet Model it has been shown that the Higgs potential can be expressed in terms of gauge-independent quantities that transform covariantly under unitary mixing of the doublets.

Higgs properties in a softly broken Inert Doublet Model [PDF]
, 2013 A bstractWe consider a model for the Higgs sector with two scalar doublets and a softly broken $ {{\mathbb{Z}}_2} $ symmetry, the Stealth Doublet Model. This model can be seen as a generalization of the Inert Doublet Model.

Exploring wrong sign scenarios in the Yukawa-Aligned 2HDM
Journal of High Energy Physics, 2023 We discuss scenarios with wrong-sign (WS) Yukawa couplings for the discovered Higgs boson in the Yukawa-aligned two Higgs doublet model. In the WS scenario, Yukawa couplings for down-type quarks and/or charged leptons have an opposite sign as compared to

The flavourful present and future of 2HDMs at the collider energy frontier
Journal of High Energy Physics, 2022 We study the intersection of flavour and collider physics for Two-Higgs-Doublet models of Type I and II. Drawing from the flavour precision-LHC exotics search complementarity, we also provide a projection of the future sensitivity that can be achieved in

Custodial symmetry breaking and Higgs boson signatures at the LHC [PDF]
Physical Review D, 2023 We discuss the simplest model that predicts a tree-level modification of the ρ parameter from a shift in the W-mass without changing the prediction for the Z mass.

Higgs Properties and Fourth Generation Leptons [PDF]
, 2011 It is possible that there are additional vectorlike generations where the quarks have mass terms that do not originate from weak symmetry breaking, but the leptons only get mass through weak symmetry breaking.

Unitarity bounds on extensions of Higgs sector
Journal of High Energy Physics, 2023 It is widely believed that extensions of the minimal Higgs sector is one of the promising directions for resolving many puzzles beyond the Standard Model (SM).
