QCD corrections to Higgs boson production and $H \to b \bar{b}$ decay in weak boson fusion / Asteriadis, Konstantin (Regensburg U.) ; Behring, Arnd (CERN) ; Melnikov, Kirill (KIT, Karlsruhe, TTP) ; Novikov, Ivan (KIT, Karlsruhe, TTP) ; Röntsch, Raoul (INFN, Milan ; Milan U.)
We study QCD corrections to the process where a Higgs boson is produced in weak boson fusion and then decays into a pair of massive $b$ quarks. [...]

A Decade of Collectivity in Small Systems / Grosse-Oetringhaus, Jan Fiete (CERN) ; Wiedemann, Urs Achim (CERN)
Signatures of collectivity, including azimuthally anisotropic and radial flow as well as characteristic hadrochemical dependencies, have been observed since long in (ultra)relativistic nucleus-nucleus collisions. [...]

Non-universal SUSY models, $g_\mu-2$, $m_H$ and dark matter / Ellis, John (King's Coll. London ; CERN) ; Olive, Keith A. (Minnesota U.) ; Spanos, Vassilis C. (Minnesota U. ; Athens U.)
We study the anomalous magnetic moment of the muon, $g_\mu - 2 \equiv 2 a_\mu$, in the context of supersymmetric models beyond the CMSSM, where the unification of either the gaugino masses $M_{1,2,3}$ or sfermion and Higgs masses is relaxed, taking into account the measured mass of the Higgs boson, $m_H$, the cosmological dark matter density and the direct detection rate.

An event generator for neutrino-induced Deep Inelastic Scattering and applications to neutrino astronomy / Ferrario Ravasio, Silvia (CERN) ; Gauld, Rhorry (Garching, Max Planck Inst.) ; Jäger, Barbara (Tubingen U.) ; Karlberg, Alexander (CERN) ; Zanderighi, Giulia (Garching, Max Planck Inst. ; Munich, Tech. U.)
We extend the recently presented, fully exclusive, next-to-leading-order accurate event generator for the simulation of massless neutral- and charged-current deep inelastic scattering (DIS) to the case of incoming neutrinos. [...]

Various scenarios of cosmic inflation enhance the amplitude of the stochastic gravitational wave background (SGWB) at frequencies detectable by the LISA detector. [...]

Towards the next Kira release / Lange, Fabian (Zurich U. ; PSI, Villigen) ; Usovitsch, Johann (CERN) ; Wu, Zihao (HIAS, UCAS, Hangzhou)
The reduction of Feynman integrals to a basis of master integrals plays a crucial role for many high-precision calculations and Kira is one of the leading tools for this task. [...]

Nonleptonic $B$-meson decays to next-to-next-to-leading order / Egner, Manuel ; Fael, Matteo (CERN) ; Schönwald, Kay (Zurich U.) ; Steinhauser, Matthias
We compute next-to-next-to-leading order QCD corrections to the partonic processes $b\to c \bar{u} d$ and $b\to c \bar{c} s$, which constitute the dominant decay channels in standard model predictions for $B$-meson lifetimes within the heavy quark expansion. [...]
