 Measurement of the e+ e- --> ZZ Production Cross Section / Loomis, C (CERN) /ALEPH The e+ e- --> ZZ cross sections at sqrt(s)=182.7 and 189 GeV have beenmeasured using the ALEPH detector and the 1997 and 1998 LEP2 datasamples representing integrated luminosities of 56.8 and 173.5 pb-1,respectively. The selections cover all of the visible ZZ final statesand yield cross section measurements of sigma_NC2(182.7 GeV) = 0.22 +- (0.18,0.22) (stat.) +- 0.04 (syst.) pb and sigma_NC2(188.6 GeV) = 0.63 +- 0.12 (stat.) +- 0.05 (syst.) pb, consistent with the Standard Model values of 0.25 and 0.63 pb, respectively.. 2005 - Published in : (2005) , pp. 1.09 Fulltext: PDF; External link: Fulltext In : Meeting of the Division of Particles and Fields (DPF) of the American Physical Society (APS), Los Angeles, CA, USA, 6 - 9 Jan 1999, pp.1.09

 Searches for GMSB at √s = 189 GeV at LEP / Taylor, Gary (UC, Santa Cruz) Searches for Gauge Mediated Supersymmetry Breaking topologies are performed on 170 pb−1 of data collected at a centre of mass energy of 188.6 GeV by each of the four LEP experiments. No evidence for such processes is found, allowing 95% C.L. lower limits to be set on the masses of various particles in the context of GMSB.

 The NA62 Calorimeter Level 0 Trigger Operation and Performances / Salamon, A (INFN, Rome2 ; Rome U., Tor Vergata) ; Aliberti, Riccardo (Mainz U.) ; Ammendola, Roberto (INFN, Rome2 ; U.

The NA62 experiment at the CERN SPS aims to measure the branching ratio of the very rare kaon decay $K^+ \rightarrow \pi^+ \nu \bar{\nu}$, collecting $\sim 100$ events with a 10\% background to make a stringent test of the Standard Model. The calorimeter level 0 trigger is used to suppress one of the main backgrounds, the $K^+ \rightarrow \pi^+ \pi^0$ decay, and to select events with a $\pi^+$ in the final state.

 Performance and recent developments of the real-time track reconstruction and alignment of the LHCb detector. / Dziurda, Agnieszka (CERN) /LHCb The LHCb detector is a single-arm forward spectrometer designed for the efficient reconstruction decays of $c$- and $b$-hadrons. For Run II (2015-2018) LHCb has introduced a novel real-time detector alignment and calibration strategy.

 The CERN Neutrino Platform / Bordoni, Stefania (CERN) The long-baseline neutrino programme has been classified as one of the four highest-priority sci- entific objectives in 2013 by the European Strategy for Particle Physics. The Neutrino Platform is the CERN venture to foster and support the next generation of accelerator-based neutrino os- cillation experiments.

Salento, Lecce (main) ; INFN, Lecce) ; Samarati, Jerome (CERN) ; Sidiropoulou, Ourania (CERN ; U. Wurzburg (main)) ; Wotschack, Joerg (CERN) With the growing diffusion of resistive Micromegas detectors in HEP experiments the study of long-term aging behaviour is becoming more and more relevant. Two resistive bulk-Micromegas detectors were installed in May 2015 at the CERN Gamma Irradiation Facility and exposed to an intense gamma irradiation with the aim to study the detector behavior under high irradiation and the long-term aging.

 Recent results from LHCb on semileptonic decays of b-hadrons / Bozzi, Concezio (INFN, Ferrara ; CERN) /LHCb Recent results on semileptonic decays of $b$ hadrons at LHCbare presented, with particular emphasis on decays involving $\tau$leptons in the final state. A new measurement of $\mathscr{R}(D^{*-} \equiv \mathscr{B}(B^0 \to D^{*-} \tau^+ \nu_{\tau}/ \mathscr{B}(B^0 \to D^{*-} \mu^+ \nu_{\mu})$ is reported, by using for the first time the $\tau$ lepton decays withthree charged pions in the final state.

The ENUBET Collaboration is developing a technology to reduce by one order of magnitude the uncertainty on fluxes in conventional neutrino beam. The ENUBET beamline exploits the large angle production of positrons from $K^+ \rightarrow e^+ \pi^0 \nu_e$ in the decay tunnel to monitor the associated production of $\nu_e$.

 New limits on heavy neutrino from NA62 / Koval, Michal (CERN) /NA62 The NA62 experiment at CERN collected large samples of charged kaon decays in flight with a minimum bias trigger configuration in 2007 and in 2015 using a completely new detector setup. Upper limits on the rate of the charged kaon decay into a muon and a heavy neutral lepton (HNL) obtained from 2007 data and limits for the charged kaon decay into an electron and a HNL obtained from 2015 data, are reported in this proceedings..
