Bounds on Lorentz invariance violation from MAGIC observation of GRB 190114C / MAGIC Collaboration
On January 14, 2019, the Major Atmospheric Gamma Imaging Cherenkov telescopes detected GRB 190114C above 0.2 TeV, recording the most energetic photons ever observed from a gamma-ray burst. [...]

Search for jet quenching effects in high multiplicity pp collisions at $\sqrt{\mathrm{s}}$=13 TeV / Jacobs, P.M.
The ALICE Collaboration reports a search for jet quenching effects in pp collisions at $\sqrt{\mathrm{s}}$=13 TeV, in events selected on high multiplicity compared to the minimum bias population. [...]

Search for physics beyond the standard model in events with jets and two same-sign or at least three charged leptons in proton-proton collisions at $\sqrt{s}=$ 13 TeV
A data sample of events from proton-proton collisions with at least two jets, and two isolated same-sign or three or more charged leptons, is studied in a search for signatures of new physics phenomena. [...]

3-D localization of radioactive hotspots via portable gamma cameras / Paradiso, V (Mirion Tech., France ; CERN) ; Amgarou, K (CEA Marcoule, Bagnols-sur-Cèze) ; Blanc de Lanaute, N (Mirion Tech., France) ; Bonnet, F (Mirion Tech., France) ; Beltramello, O (CERN) ; Liénard, E (Caen U.)
A portable stereo gamma camera has been built, based on two hybrid pixelated detectors, each of them comprising a 1 mm thick CdTe substrate bump-bonded to the Timepix readout chip, a pixelated CMOS ASIC consisting of 256 × 256 pixels with 55 µm pitch. The technique described in this paper allows the automatic estimation of the distances between the prototype and the located radioactive sources by using triangulation based on epipolar geometry.

We present phenomenological results for the inclusive cross section for the production of a lepton-pair via virtual photon exchange at next-to-next-to-next-to-leading order (N$^3$LO) in perturbative QCD. [...]

Black holes (often) saturate entanglement entropy the fastest / Mezei, Márk (SUNY, Stony Brook) ; van der Schee, Wilke (CERN)
There is a simple bound on how fast the entanglement entropy of a subregion of a many-body quantum system can saturate in a quench: $t_\text{sat}\geq R/v_B$, where $t_\text{sat}$ is the saturation time, $R$ the radius of the largest inscribed sphere, and $v_B$ the butterfly velocity characterizing operator growth.

Baryon production from small to large collision systems at ALICE / Vazquez Rueda, Omar (Lund U.)
Studies of the production of light- and heavy-flavor baryons are of prominent importance to characterize the partonic phase created in ultrarelativistic heavy-ion collisions and to investigate hadronization mechanisms at the LHC. [...]
