Kinematic twist-three contributions to pseudo- and quasi-GPDs and translation invariance

open access: yesJournal 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 ...

Sivers, Boer-Mulders and worm-gear distributions at next-to-leading order

open access: yesJournal 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.

Excited Baryons Phenomenology from Large-$N_c$ QCD [PDF]

open access: yes, 1997
We present a phenomenological analysis of the strong couplings of the negative-parity L=1 baryons from the perspective of the large-$N_c$ expansion. In the large-$N_c$ limit the mass spectrum and mixing pattern of these states are constrained in a very ...

Phenomenology of t t ¯ j $$ t\overline{t}j $$ + X production at the LHC

open access: yesJournal 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 $$ t\overline{t}j $$ +

The Low‐Scale Seesaw Solution to the MW$M_W$ and (g−2)μ$(g-2)_\umu$ Anomalies

open access: yesFortschritte 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

open access: yesFortschritte 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

open access: yesAdvances 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

open access: yesJournal 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

open access: yesHuman 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

open access: yesAdvances 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 ...
