 Elliptic flow of charm and strange hadrons in high-multiplicity pPb collisions at ${\sqrt {\smash [b]{s_{_{\mathrm {NN}}}}}} =$ 8.16 TeV The elliptic azimuthal anisotropy coefficient ($v_2$) is measured for charm (${\mathrm{D^0}}$) and strange (${\mathrm{K^0_S}}$, $\Lambda$, $\Xi^-$, and $\Omega^-$) hadrons, using a data sample of pPb collisions collected by the CMS experiment, at a nucleon-nucleon center-of-mass energy ${\sqrt {\smash [b]{s_{_{\mathrm {NN}}}}}} =$ 8.16 TeV.

 Measurement of $\Upsilon$ production in $pp$ collisions at $\sqrt{s}$= 13 TeV / LHCb Collaboration The production cross-sections of $\Upsilon(1S)$, $\Upsilon(2S)$ and $\Upsilon(3S)$ mesons in proton-proton collisions at $\sqrt{s}$= 13 TeV are measured with a data sample corresponding to an integrated luminosity of $277 \pm 11$ $\rm pb^{-1}$ recorded by the LHCb experiment in 2015.

 Exploiting the WH/ZH symmetry in the search for New Physics / Harlander, R.V. (Aachen, Tech. Hochsch.) ; Klappert, J. (Aachen, Tech. Hochsch.) ; Pandini, C. (CERN) ; Papaefstathiou, A. (Amsterdam U. ; NIKHEF, Amsterdam) We suggest to isolate the loop-induced gluon-initiated component ($gg\to ZH$) for associated $ZH$ production by using the similarity of the Drell-Yan-like component for $ZH$ production to the $WH$ process.

 Hawking radiation and propagation of massive charged scalar field on a three-dimensional G\"odel black hole / González, P.A. (Diego Portales U.) ; Övgün, Ali (CERN ; Eastern Mediterranean U. ; Valparaiso U., Catolica) ; Saavedra, Joel (Valparaiso U., Catolica) ; Vásquez, Yerko (La Serena U.) In this paper we consider the three-dimensional G\"odel black hole as a background and we study the vector particle tunneling from this background in order to obtain the Hawking temperature.
