LISA Sensitivity to Gravitational Waves from Sound Waves / Schmitz, Kai
Gravitational waves (GWs) produced by sound waves in the primordial plasma during a strong first-order phase transition in the early Universe are going to be a main target of the upcoming Laser Interferometer Space Antenna (LISA) experiment. [...]

Predictions for $\mathrm{Z}$-boson production in association with a $\mathrm{b}$-jet at $\mathcal{O}(\alpha_s^3)$ / Gauld, R. ; Gehrmann-De Ridder, A. ; Glover, E.W.N. ; Huss, A. ; Majer, I.
Fixed-order predictions are provided for the associated production of a $\mathrm{Z}$-boson and a $\mathrm{b}$-jet at $\mathcal{O}(\alpha_s^3)$ in perturbative QCD, obtained by combining a massless next-to-next-to-leading order and a massive next-to-leading order calculation. [...]

The Fully-Differential Gluon Beam Function at NNLO / Gaunt, Jonathan R. (CERN) ; Stahlhofen, Maximilian (Freiburg U.)
The fully-differential beam function (dBF) is a universal ingredient in resummed predictions of hadron collider observables that probe the full kinematics of the incoming parton from each colliding proton -- the virtuality and transverse momentum as well as the light-cone momentum fraction $x$. [...]

New result on phase shift analysis / Martin, André (CERN) ; Richard, Jean-Marc (IP2I, Lyon)
Assuming a certain continuity property, we prove, using the old results of Itzykson and Martin, that, except for an obvious ambiguity, there are only at most two amplitudes reproducing an elastic differential cross section at a given energy..
