Measurement of multijet azimuthal correlations and determination of the strong coupling in proton-proton collisions at √s=13TeV

Jan Steggemann, Konstantin Androsov, Anna Mascellani, Joanna Malgorzata Wanczyk

A measurement is presented of a ratio observable that provides a measure of the azimuthal correlations among jets with large transverse momentum p(T). This observable is measured in multijet events over the range of p(T) = 360-3170 GeV based on data collec ...

Observation of ψ(3686) → Ω(-)K(+) Ξ 0 + c.c

Yunxuan Song

Using (27.12 +/- 0.14) x 10(8) ψ(3686) events collected with the BESIII detector at BEPCII, the decay of ψ(3686) -> Ω(-)K(+) Ξ 0 + c.c. is observed for the first time. The branching fraction of this decay is measured to be B-Psi(3686)->Omega K--(+)Xi

Multichannel Radiation-Compensated Systems for Temperature and Humidity Monitoring for High Energy Physics Detectors

Sandro Carrara, Amar Kapic

Monitoring humidity and temperature in silicon-based high-energy physics (HEP) detectors is indispensable but challenging due to space restrictions, radiation, sub-zero temperatures, and strong magnetic fields. This manuscript presents humidity and tempera ...

Revealing higher-order light and matter energy exchanges using quantum trajectories in ultrastrong coupling

Fabrizio Minganti

The dynamics of open quantum systems is often modeled using master equations, which describe the expected outcome of an experiment (i.e., the average over many realizations of the same dynamics). Quantum trajectories, instead, model the outcome of ideal si ...
