 RE3/1 and RE4/1 RPC chambers integration in the inner region of the forward muon spectrometer in the CMS experiment / Voevodina, E. ; Crotty, I. The high pseudorapidity ($\eta$) region of the Compact Muon Solenoid (CMS) muon system is covered by Cathode Strip Chambers only and lacks redundant coverage despite the fact that it is a challenging region for muons in terms of backgrounds and momentum resolution.

 Sphere Packing and Quantum Gravity / Hartman, Thomas (Cornell U., Phys. Dept.) ; Mazáč, Dalimil (YITP, Stony Brook ; Stony Brook U., New York, SCGP) ; Rastelli, Leonardo (YITP, Stony Brook ; CERN) We establish a precise relation between the modular bootstrap, used to constrain the spectrum of 2D CFTs, and the sphere packing problem in Euclidean geometry.

 Flavored Axions / Ziegler, Robert (CERN) Precision flavor experiments can look for the QCD axion complementarily to usual searches with axion helio- and haloscopes, allowing to test PQ breaking scales as high as $10^{12} \, {\rm GeV}$. [...] arXiv:1905.01084. - 8 p. Fulltext

 Temperature dependence of $\eta/s$: uncertainties from the equation of state / Auvinen, Jussi (Belgrade, Inst. Phys.) ; Eskola, Kari J. (Helsinki U. ; Helsinki Inst. of Phys.) ; Huovinen, Pasi (Wroclaw U.) ; Niemi, Harri (Helsinki U. ; Helsinki Inst. of Phys.) ; Paatelainen, Risto (CERN) ; Petreczky, Péter (Brookhaven) We perform a global model-to-data comparison on Au+Au collisions at $\sqrt{s_{NN}}=200$ GeV and Pb+Pb collisions at $2.76$ TeV and $5.02$ TeV, using a 2+1D hydrodynamics model with the EKRT initial state and a shear viscosity over entropy density ratio $(\eta/s)(T)$ with a linear $T$ dependence.
