 (YSF) Search for additional neutral MSSM Higgs bosons in the di-tau final state at CMS / Spanring, Markus (Vienna, OAW) /CMS Collaboration A search for aditional neutral Higgs bosons in the $\tau\tau$ final state is presented. The search is performed in the context of the minimal supersymmetric extension of the standard model (MSSM), using data from proton-proton collison collected with the CMS detector in 2016 at a center-of-mass energy of 13~TeV.

 Testing the system size dependence of hydrodynamical expansion and thermal particle production with $\pi$, K, p, and $\phi$ in Xe-Xe and Pb-Pb collisions with ALICE / Bellini, F. We present new results on transverse momentum spectra, integrated yields, and mean transverse momenta of pions, kaons, and protons, as well as of $\phi$-mesons for various centrality classes measured in Pb-Pb and Xe-Xe collisions at the LHC.
