 CP-violating Higgs-gauge boson couplings in $H\nu \bar{\nu}$ production at three energy stages of CLIC / Karadeniz, Ozgun (Bolu Abant Izzet Baysal University) ; Senol, Abdulkadir (Abant Izzet Baysal University (TR)) ; Oyulmaz, Kaan Yuksel (Abant Izzet Baysal University (TR)) ; Denizli, Haluk (Ankara University Institute of Accelerator Technologies (TR)) A phenomenological study of CP-violating dimension-six operators via the $e^+e^−$ → $\nu \bar{\nu} H$ process is performed in a model-independent Standard Model effective field theory framework at all energy stages of CLIC using the updated baseline integrated luminosities. All signal and relevant background events are generated in MadGraph5_aMC@NLO and passed through PYTHIA 8 for parton showering and hadronization at parton level.

 Bayesian unfolding of charged particle $p_{\mathrm{T}}$ spectra with ALICE at the LHC / Krüger, Mario The study of the Quark-Gluon Plasma created in ultrarelativistic heavy-ion collisions at the CERN-LHC is complemented by reference measurements in proton-lead (p--Pb) and proton-proton (pp) collisions, where the effects of multiple-parton interactions and hadronization beyond independent string fragmentation can be investigated.

 Strong constraints on the $K^0_s \to \mu^+ \mu^-$ branching fraction /LHCb Collaboration A search for the decay $K^0_s \to \mu^+ \mu^-$ is performed using proton-proton collision data, corresponding to an integrated luminosity of $5.6 \, \text {fb}^{-1}$, collected with the LHCb experiment during 2016, 2017 and 2018 at a center-of-mass energy of $13\,\mathrm{TeV}$. The observed number of signal decays is consistent with zero, yielding an upper limit of $\mathcal {B}( K^0_s \to \mu^+ \mu^-) < 2.2\,(2.6)\times 10^{-10}$ at $90$ $(95)\% ~\text {CL}$ [...] LHCb-CONF-2019-002; CERN-LHCb-CONF-2019-002.- Geneva : CERN, 2019 - 9.

 Strangeness Production in Jets and Underlying Events in pp Collisions at $\sqrt{s}$ = 13 TeV with ALICE / Cui, Pengyao The production of $\mathrm{K^0_S}$, $\Lambda$ and $\Xi$ is measured in jets and underlying events in pp collisions at $\sqrt{s}$ = 13 TeV with ALICE detectors.

 Directionally Accelerated Detection of an Unknown Second Reactor with Antineutrinos for Mid-Field Nonproliferation Monitoring / Rare Event Detection Group, Lawrence Livermore National Laboratory Collaboration When monitoring a reactor site for nuclear nonproliferation purposes, the presence of an unknown or hidden nuclear reactor could be obscured by the activities of a known reactor of much greater power nearby.

 Higgs transverse momentum with a jet veto: a double-differential resummation / Monni, Pier Francesco ; Rottoli, Luca ; Torrielli, Paolo We consider the simultaneous measurement of the Higgs ($p_t^{\tiny{\mbox{H}}}$) and the leading jet ($p_t^{\tiny{\mbox{J}}}$) transverse momentum in hadronic Higgs-boson production, and perform the resummation of the large logarithmic corrections that originate in the limit $p_t^{\tiny{\mbox{H}}}\,,p_t^{\tiny{\mbox{J}}} \ll m_{\tiny{\mbox{H}}}$ up to next-to-next-to-leading-logarithmic order.
