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. (Nikhef, Amsterdam) ; Gehrmann-De Ridder, A. (Zurich, ETH ; Zurich U.) ; Glover, E.W. N. (Durham U., IPPP) ; Huss, A. (Durham U., IPPP ; CERN) ; Majer, I. (Zurich, ETH)
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 $x$. [...]

London ; CERN ; NICPB, Tallinn) ; Ghosh, D.K. (IACS, Kolkata) ; Masełek, R. (Warsaw U.) ; Panizzo, G. (ICTP, Trieste ; INFN, Trieste) ; Pinfold, J.L. (Alberta U.) ; Sakurai, K. (Warsaw U.) ; Shaa, A. (Warsaw U.) ; Wall, A. (Alabama U.)
We study the prospects of searches for exotic long-lived particles with the MoEDAL detector at the LHC, assuming the integrated luminosity of 30 fb$^{-1}$ that is expected at the end of Run 3. [...]
