 Search for associated production of dark matter with a Higgs boson decaying to $\mathrm{b}\overline{\mathrm{b}}$ or $\gamma \gamma$ at $\sqrt{s}=13$ TeV / CMS Collaboration A search for dark matter is performed using events with large missing transverse momentum and a Higgs boson decaying either to a pair of bottom quarks or to a pair of photons. The data from proton-proton collisions at a center-of-mass energy of 13 TeV, collected in 2015 with the CMS detector at the LHC, correspond to an integrated luminosity of 2.3 inverse femtobarns.

 Comments concerning the paper ”Measurement of negatively charged pion spectra in inelastic p+p interactions at 20, 31, 40, 80 and 158 GeV/c” by the NA61 collaboration / Fischer, H G (CERN) ; Makariev, M (Sofiya, Inst. Nucl. Res.) ; Varga, D (Budapest, RMKI) ; Wenig, S (CERN) New data from the NA61 collaboration on the production of negative pions in p+p interactions at beam momenta between 20 and 158 GeV/c are critically compared to available results in the same energy range. It is concluded that the NA61 data do not come up to the quality of the existing work. [...] arXiv:1401.3192; CERN-PH-EP-2013-225.- Geneva : CERN, 2014 - 16.

 Real-Time Use of GPUs in NA62 Experiment / Pantaleo, F (CERN) ; Collazuol, G (Padua U.) ; Innocente, V (CERN) ; Lamanna, G (CERN) ; Sozzi, M (Pisa U.) We describe a pilot project for the use of GPUs in a real-time triggering application in the early trigger stages at the CERN NA62 experiment, and the results of the first field tests together with a prototype data acquisition (DAQ) system.

 Further Evidence for Low Energy Protonium Production in Vacuum / Lodi Rizzini, Evandro (U. Brescia ; INFN, Brescia) ; Venturelli, Luca (U. Brescia ; INFN, Brescia) ; Zurlo, Nicola (U. Brescia ; INFN, Brescia) ; Charlton, Michael (Swansea U.) ; Amsler, Claude, (Zurich U.) ; Bonomi, Germano (Brescia U. ; INFN, Pavia) ; Canali, Carlo (Zurich U.) ; Carraro, Carlo (INFN, Genoa ; Genoa U.) ; Fontana, Andrea (INFN, Pavia) ; Genova, Pablo (INFN, Pavia ; Pavia U.) et al. We describe an experiment performed in the ATHENA apparatus in which there is evidence that the antiproton-proton bound state, protonium, has been produced at very low energies in vacuum following the interaction of cold antiprotons with a trapped cloud of molecular hydrogen ions.
