Light-front approach to axial-vector quarkonium γ * γ * form factors
Journal of High Energy Physics, 2022 In this work, we perform a detailed study of transition form factors for axial- vector meson production via the two-photon fusion process γ * γ * → 1++, with space-like virtual photons in the initial state and a P-wave axial-vector quarkonium in the ...

On the polarization of the non-prompt contribution to inclusive J/ψ production in pp collisions
Journal of High Energy Physics, 2022 Of the J/ψ mesons (inclusively) produced in pp collisions, a big fraction results from B decays, increasing with transverse momentum and exceeding 50% for p T > 20 GeV.

Kinematic twist-three contributions to pseudo- and quasi-GPDs and translation invariance
Journal of High Energy Physics, 2023 We present explicit expressions for the tree-level “kinematic” twist-three contributions to the nucleon matrix elements of gauge-invariant nonlocal quark-antiquark operators which can be used in lattice calculations of generalized parton distributions ...

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.

Sivers, Boer-Mulders and worm-gear distributions at next-to-leading order
Journal of High Energy Physics, 2023 We compute the Sivers, Boer-Mulders, worm-gear (T and L) transverse momentum dependent distributions in terms of twist-two and twist-three collinear distributions in the small-b limit up to next-to-leading order (NLO) in perturbation theory.

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.

Phenomenology of t t ¯ j $$ t\overline{t}j $$ + X production at the LHC
Journal of High Energy Physics, 2022 We present phenomenological results for t t ¯ j $$ t\overline{t}j $$ + X production at the Large Hadron Collider, of interest for designing forthcoming experimental analyses of this process. We focus on those cases where the t t ¯ j $$ t\overline{t}j $$ +

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.

Parton distributions with scale uncertainties: a Monte Carlo sampling approach
Journal of High Energy Physics, 2023 We present the MCscales approach for incorporating scale uncertainties in parton distribution functions (PDFs). The new methodology builds on the Monte Carlo sampling for propagating experimental uncertainties into the PDF space that underlies the NNPDF ...

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.
