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. [...]

Leading-logarithmic threshold resummation of Higgs production in gluon fusion at next-to-leading power / Beneke, Martin (Munich, Tech. U.) ; Garny, Mathias (Munich, Tech. U.) ; Jaskiewicz, Sebastian (Munich, Tech. U.) ; Szafron, Robert (Munich, Tech. U. ; CERN) ; Vernazza, Leonardo (Nikhef, Amsterdam ; Amsterdam U. ; INFN, Turin ; Turin U.) ; Wang, Jian (Shandong U.)
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. [...]

Sommerfeld-corrected relic abundance of wino dark matter with NLO electroweak potentials / Beneke, Martin (Munich, Tech. U.) ; Szafron, Robert (CERN) ; Urban, Kai (Munich, Tech. U.)
Extending previous work, we calculate the electroweak potentials for all co-annihilation channels of wino dark matter at the one-loop order and obtain the wino relic abundance including the Sommerfeld effect at the next-to-leading order (NLO)..

NNLL resummation for the associated production of a top pair with a heavy boson at the LHC / Broggio, Alessandro (Munich, Tech. U.)
In this presentation we review recent results on the resummation of soft gluon emission corrections for the associated production of a top-quark pair with a heavy boson (Higgs/W/Z) at the Large Hadron Collider (LHC). We develop a parton level Monte Carlo based on a soft-gluon resummation formula valid up to next-to-next-to-leading logarithmic (NNLL) accuracy. [...]

Momentum-space threshold resummation in $tW$ production at the LHC / Li, Chong Sheng (Peking U., SKLNPT ; Peking U., CHEP) ; Li, Hai Tao (Los Alamos) ; Shao, Ding Yu (CERN) ; Wang, Jian (Munich, Tech. U.)
We calculate the soft-gluon corrections for $tW$ production to all orders. The soft limit is defined in the pair invariant mass or one particle inclusive kinematic schemes. [...]

Triple-real contribution to the quark beam function in QCD at next-to-next-to-next-to-leading order / Melnikov, Kirill (KIT, Karlsruhe) ; Rietkerk, Robbert (KIT, Karlsruhe) ; Tancredi, Lorenzo (CERN) ; Wever, Christopher (Munich, Tech. U.)
We compute the three-loop master integrals required for the calculation of the triple-real contribution to the N$^3$LO quark beam function due to the splitting of a quark into a virtual quark and three collinear gluons, $q \to q^*+ggg$. This provides an important ingredient for the calculation of the leading-color contribution to the quark beam function at N$^3$LO..

A multi-component SIMP model with $U(1)_X \rightarrow Z_2 \times Z_3$ / Choi, Soo-Min (Munich, Tech. U.) ; Kim, Jinsu (CERN) ; Ko, Pyungwon (Korea Inst. Advanced Study, Seoul) ; Li, Jinmian (Sichuan U.)
Multi-component dark matter scenarios are studied in the model with $U(1)_X$ dark gauge symmetry that is broken into its product subgroup $Z_2 \times Z_3$á la Krauss-Wilczek mechanism. In this setup, there exist two types of dark matter fields, $X$ and $Y$, distinguished by different $Z_2 \times Z_3$ charges. [...]

Gravitational waves from decaying sources in strong phase transitions / Caprini, Chiara (Geneva U. ; CERN) ; Jinno, Ryusuke (Kobe U.) ; Konstandin, Thomas (DESY) ; Roper Pol, Alberto (Geneva U.) ; Rubira, Henrique (Munich, Tech. U.) ; Stomberg, Isak (DESY)
We study the generation of gravitational waves (GWs) during a first-order cosmological phase transition (PT) using the recently introduced Higgsless approach to numerically evaluate the fluid motion induced by the PT. [...]

The dark matter bispectrum from effective viscosity and one-particle irreducible vertices / Floerchinger, Stefan (U. Heidelberg, ITP) ; Garny, Mathias (Munich, Tech. U.) ; Katsis, Aris (Athens U.) ; Tetradis, Nikolaos (Athens U.) ; Wiedemann, Urs Achim (CERN)
Dark matter evolution during the process of cosmological structure formation can be described in terms of a one-particle irreducible effective action at a characteristic scale $k_m$ and a loop expansion below this scale, based on the effective propagators and vertices. We calculate the form of the effective vertices and compute the bispectrum of density perturbations within a one-loop approximation. [...]
