A realistic coalescence model for deuteron production
/ Mahlein, Maximilian (Munich, Tech. U.) ; Barioglio, Luca (Munich, Tech. U. ; INFN, Turin) ; Bellini, Francesca (INFN, Bologna) ; Fabbietti, Laura (Munich, Tech. U.) ; Pinto, Chiara (Munich, Tech. U.) ; Singh, Bhawani (Munich, Tech. U.) ; Tripathy, Sushanta (INFN, Bologna ; CERN)
A microscopic understanding of (anti)deuteron production in hadron-hadron collisions is the subject of many experimental and theoretical efforts in nuclear physics. This topic is also very relevant for astrophysics, since the rare production of antinuclei in our Universe could be a doorway to discover new physics. [...]

Leading-logarithmic threshold resummation of Higgs production in gluon fusion at next-to-leading power

We sum the leading logarithms $\alpha_s^n \ln^{2 n-1}(1-z), n = 1,2,$... near the kinematic threshold $z=m_H^2/\hat{s}\to 1$ at next-to-leading power in the expansion in (1$-z$) for Higgs production in gluon fusion. [...]

Supplemental material: afterburner for generating light (anti-)nuclei with QCD-inspired event generators in pp collisions
/ALICE Collaboration
This note complements the paper titled: ``Production of deuterons, tritons, $^{3}$He nuclei and their anti-nuclei in pp collisions at $\sqrt{s}$~=~0.9, 2.76 and 7~TeV'' with additional material related to Monte Carlo simulations necessary to compare the results with lower energy experiments. It describes a coalescence-based afterburner for QCD-inspired event generators, which allows the generation of light nuclei, hyper-nuclei and their charge conjugates in proton--proton (pp) collisions at LHC energies. [...]

Large-x resummation of off-diagonal deep-inelastic parton scattering from d-dimensional refactorization
/ Beneke, Martin (Munich, Tech. U.) ; Garny, Mathias (Munich, Tech. U.) ; Jaskiewicz, Sebastian (Munich, Tech. U.) ; Szafron, Robert (CERN) ; Vernazza, Leonardo (INFN, Turin ; Turin U.) ; Wang, Jian (Shandong U.)
The off-diagonal parton-scattering channels $g+\gamma^*$ and $q+\phi^*$ in deep-inelastic scattering are power-suppressed near threshold $x\to 1$. We address the next-to-leading power (NLP) resummation of large double logarithms of $1-x$ to all orders in the strong coupling, which are present even in the off-diagonal DGLAP splitting kernels.
