 The new inner tracking system for the ALICE upgrade at the LHC / Di Mauro, A (CERN) /ALICE ALICE, the CERN LHC experiment devoted to the study of the QGP (Quark–Gluon Plasma) properties, will undergo a comprehensive upgrade during the second long shutdown of the LHC (in 2019–2020) to enhance the capability for high precision measurements of rare processes at low transverse momenta ($P_{T}$). One of the key elements of the upgrade strategy is the novel, high-resolution, ultra-light Inner Tracking System (ITS) consisting of seven concentric layers of Monolithic Active Pixel Sensors (MAPS) covering a total active area of 10 m$^{2}$ segmented in 12.5 Gpixels.

 Results on $b$ hadron properties in CMS / Madlener, Thomas (Vienna, OAW) /CMS The lifetime is among the fundamental properties of particles and is one of the important observables in heavy hadrons allowing to test the theoretical tools describing their physics. This report presents lifetime measurements of $B^0,B_{s}^{0},\Lambda _{b}^{0}$ and $B_{c}^{+}$ hadrons performed on data, corresponding to 19.7 fb$-^{1}$, collected by the CMS experiment at the LHC at a center-of-mass energy of √s = 8 TeV.

 Precision laser spectroscopy experiments on antiprotonic helium / Hori, Masaki (Munich, Max Planck Inst. Quantenopt.) At CERN‘s Antiproton Decelerator (AD) facility, the Atomic Spectroscopyand Collisions Using Slow Antiprotons (ASACUSA) collaboration is carrying out precise laser spectroscopy experiments on antiprotonic helium ($\bar{p}He^+\equiv \bar{p} + He^{2+}+e^-$) atoms. By employing buffer-gas cooling techniquesin a cryogenic gas target, samples of atoms were cooled to temperatureT = 1.5–1.7 K, thereby reducing the Doppler width in the single-photon resonance lines.

The data collected with different trigger configuration allow to search for both long and short living heavy neutrinos in the mass range below the kaon mass.

 The SHiP physics program / De Lellis, Giovanni (INFN, Naples ; Naples U.) The discovery of the Higgs boson has fully confirmed the Standard Model of particles and fields. Nevertheless, there are still fundamental phenomena, like the existence of dark matter and the baryon asymmetry of the Universe, which deserve an explanation that could come from the discovery of new particles.

 HVP contribution of the light quarks to the muon $(g - 2)$ including isospin-breaking corrections with Twisted-Mass fermions / Giusti, Davide (Rome III U. ; INFN, Rome3) ; Lubicz, Vittorio (Rome III U. ; INFN, Rome3) ; Martinelli, Guido (Rome U. ; INFN, Rome) ; Sanfilippo, Francesco (INFN, Rome3) ; Simula, Silvano (INFN, Rome3) ; Tarantino, Cecilia (Rome III U. ; INFN, Rome3) We present a preliminary lattice calculation of the leading-order electromagnetic and strong isospin-breaking corrections to the Hadronic Vacuum Polarization (HVP) contribution of the light quarks to the anomalous magnetic moment of the muon. The results are obtained in the quenched-$QED$ approximation using the $QCD$ gauge configurations generated by the European Twisted Mass Collaboration (ETMC) with $N_f = 2 + 1 + 1$ dynamical quarks, at three values of the lattice spacing varying from $0.089$ to $0.062 ~ \mbox{fm}$, at several lattice volumes and with pion masses in the range $M_\pi \simeq 220 \div 490 ~ \mbox{MeV}$.. arXiv:1810.05880.- SISSA, 2019-05-29 - 7 p. - Published in : PoS LATTICE2018 (2018) 140 Fulltext: PoS(LATTICE2018)140 - PDF; 1810.05880 - PDF; In : 36th International Symposium on Lattice Field Theory, East Lansing, MI, USA, 22 - 28 Jul 2018, pp.140
