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.

Stability of the Next‐to‐Tribimaximal Mixings under Radiative Corrections with the Variation of the SUSY Breaking Scale in MSSM

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 ...

QCD equation of state and dark matter [PDF]

, 2012
The QCD equation of state is not often discussed in cosmology. However, the relic density of weakly interacting massive particles (WIMPs) depends on the entropy and the expansion rate of the Universe when they freeze out, at a temperature in the range ...

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 ...

Interplay of nuclear physics, effective field theories, phenomenology, and lattice QCD in neutrino physics [PDF]

, 2022
Experiments in neutrino physics cover a wide range—from deep inelastic scattering, over long base-line oscillation experiments and low-energy coherent neutrino–nucleus scattering (CEνNS), to searches for neutrinoless double β decay (0νββ)—yet in all ...

Hadronic vacuum polarization and the MUonE proposal

Journal of High Energy Physics, 2022
The MUonE proposal at the CERN SPS consists in extracting the value of the hadronic vacuum polarization self-energy function (HVP) from its contribution to the differential cross-section of elastic muon-electron scattering.
