The Low‐Scale Seesaw Solution to the MW$M_W$ and (g−2)μ$(g-2)_\umu$ Anomalies
Fortschritte der Physik, Volume 71, Issue 4-5, May 2023., 2023 Abstract The recent CDF‐II measurement of the W‐boson mass shows a strong tension with the corresponding Standard Model prediction. Once active neutrino masses are explained in the context of the Low‐Scale Seesaw mechanisms, this tension can be resolved.

Probing HNL‐ALP Couplings at Colliders
Fortschritte der Physik, Volume 71, Issue 4-5, May 2023., 2023 Abstract Axion‐like particles (ALPs) and heavy neutral leptons (HNLs) are both well‐motivated extensions of the Standard Model. As ALPs couple to on‐shell fermions proportionally to their masses, processes involving both types of particles may give rise, for TeV HNLs, to relevant phenomenology at colliders.

Advances in High Energy Physics, Volume 2023, Issue 1, 2023., 2023 We analyze the radiative stability of the next‐to‐tribimaximal mixings (NTBM) with the variation of the SUSY breaking scale (mS) in MSSM, for both normal ordering (NO) and inverted ordering (IO) at the fixed input value of the seesaw scale MR = 1015 GeV and two different values of tanβ.

Sex is a defining feature of neuroimaging phenotypes in major brain disorders
Human Brain Mapping, Volume 43, Issue 1, Page 500-542, January 2022., 2022 Here, we review the human neuroimaging literature examining sex effects on adult brain structure using structural and diffusion MRI. We discuss normative sex differences based on population‐based studies as well as sex differences in 14 major brain diseases.

Generalising Holographic Superconductors
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 In this paper we propose a generalised holographic framework to describe superconductors. We first unify the description of s‐, p‐, and d‐wave superconductors in a way that can be easily promoted to higher spin. Using a semianalytical procedure to compute the superconductor properties, we are able to further generalise the geometric description of the ...

Discovery and Exclusion Prospects for Staus Produced by Heavy Higgs Boson Decays at the LHC
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 In a previous work, we developed a search strategy for staus produced by the decay of the heavy CP‐even Higgs boson H within the context of the large tanβ regime of the minimal supersymmetric standard model (MSSM) in a scenario of large stau mixing. Here, we study the performance of such search strategy by confronting it with the complementary mixing ...

On the Impact of the LHC Run 2 Data on General Composite Higgs Scenarios
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 We study the impact of Run 2 LHC data on general composite Higgs scenarios, where nonlinear effects, mixing with additional scalars, and new fermionic degrees of freedom could simultaneously contribute to the modification of Higgs properties. We obtain new experimental limits on the scale of compositeness, the mixing with singlets and doublets with the

On the Interpretation of Nonresonant Phenomena at Colliders
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 With null results in resonance searches at the LHC, the physics potential focus is now shifting towards the interpretation of nonresonant phenomena. An example of such shift is the increased popularity of the EFT programme. We can embark on such programme owing to the good integrated luminosity and an excellent understanding of the detectors, which ...

Study of Bs⟶ϕℓ+ℓ− Decays in the PQCD Factorization Approach with Lattice QCD Input
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 In this paper, we studied systematically the semileptonic decays Bs⟶ϕl+l− with l− = (e−, μ−, τ−) by using the perturbative QCD (PQCD) and the “PQCD+Lattice” factorization approach, respectively. We first evaluated all relevant form factors Fi(q2) in the low‐q2 region using the PQCD approach, and we also took the available lattice QCD results at the ...

Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 We investigate the exclusive semileptonic and rare D⟶π(K) decays within the standard model together with the light‐front quark model (LFQM) constrained by the variational principle for the QCD‐motivated effective Hamiltonian. The form factors are obtained in the q+ = 0 frame and then analytically continue to the physical timelike region.
