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 $10^{12} \, {\rm GeV}$. [...]

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.

Production of muons from heavy-flavour hadron decays in pp collisions at $\sqrt{s}=5.02$ TeV / ALICE Collaboration
Production cross sections of muons from semi-leptonic decays of charm and beauty hadrons were measured at forward rapidity ($2.5<y<4$) in proton--proton (pp) collisions at a centre-of-mass energy $\sqrt{s}=5.02$ TeV with the ALICE detector at the CERN LHC. [...]

Search for a light charged Higgs boson decaying to a W boson and a CP-odd Higgs boson in final states with $\mathrm{e}\mu\mu$ or $ \mu\mu\mu$ in proton-proton collisions at $\sqrt{s} = $ 13 TeV / CMS Collaboration
A search for a light charged Higgs boson ($\mathrm{H}^{+}$) decaying to a W boson and a CP-odd Higgs boson (A) in final states with $\mathrm{e}\mu\mu$ or $ \mu\mu\mu$ is performed using data from pp collisions at $\sqrt{s} = $ 13 TeV, recorded by the CMS detector at the LHC and corresponding to an integrated luminosity of 35.9 fb$^{-1}$.

Search for the electroweak diboson production in association with a high-mass dijet system in semileptonic final states in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector / ATLAS Collaboration
This paper reports on a search for the electroweak diboson ($WW/WZ/ZZ$) production in association with a high-mass dijet system, using data from proton-proton collisions at a center-of-mass energy of $\sqrt{s}=13$ TeV. [...]
