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 ...

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.

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 $$ t\overline{t}j $$ +

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 ...

Non-factorisable effects in the decays B ¯ s 0 → D s + π − $$ {\overline{B}}_s^0\to {D}_s^{+}{\pi}^{-} $$ and B ¯ 0 → D + K − $$ {\overline{B}}^0\to {D}^{+}{K}^{-} $$ from LCSR

Journal of High Energy Physics, 2023
In light of the current discrepancies between the recent predictions based on QCD factorisation (QCDF) and the experimental data for several non-leptonic colour-allowed two-body B-meson decays, we obtain new determinations of the non-factorisable soft ...

Vectorlike Confinement at the LHC [PDF]

, 2010
We argue for the plausibility of a broad class of vectorlike confining gauge theories at the TeV scale which interact with the Standard Model predominantly via gauge interactions.

A guide to diagnosing colored resonances at hadron colliders

Journal of High Energy Physics, 2023
We present a comprehensive study on how to distinguish the properties of heavy dijet resonances at hadron colliders. A variety of spins, chiral couplings, charges, and QCD color representations are considered.

Gravitational transition form factors of N → ∆ via QCD light-cone sum rules

Journal of High Energy Physics, 2023
We present the first direct calculation on the gravitational form factors (GFFs) of the N → ∆ transition using an analytic method, the QCD light-cone sum rules. The matrix element of the quark part of the energy momentum tensor current sandwiched between
