[in2p3-00014365] Search for exclusive decays of the $\Lambda_{b}$ baryon and measurement of its mass

22 mars 2019

A search for fully reconstructed \lb beauty baryons is performed using about 3 million Z decays collected with the DELPHI detector at LEP. The analysis relies on the combined use of the accurate tracking and of the hadron identification capabilities of DELPHI. A total of four events has been (...)

[in2p3-00003430] Measurement of $\mid V_{cs} \mid$ using W decays at LEP2

21 mars 2019

Decays of $W^\pm$ bosons, produced at LEP2, have been used to measure the $|V_cs|$ element of the Cabibbo-Kobayashi-Maskawa matrix. Values for $|V_cs|$ were extracted both from the measured hadronic branching ratio of $W^\pm$ decays and by tagging the flavour of hadronic jets produced in (...)

[in2p3-00008013] Search for R-parity violation with a $\bar{U} \bar{D} \bar{D}$ coupling at $\sqrt{s}$ = 189 GeV

21 mars 2019

Searches for pair production of gauginos and squarks in $e^+ e^-$ collisions at a centre-of-mass energy of 189 GeV have been performed on data corresponding to an integrated luminosity of 158 pb$^-1$ collected by the DELPHI detector at LEP. The data were analyzed under the assumption of (...)

[hal-02073505] Search for a heavy pseudoscalar boson decaying to a Z and a Higgs boson at $\sqrt{s}=$ 13 TeV

21 mars 2019

A search is presented for a heavy pseudoscalar boson A decaying to a Z boson and the standard model Higgs boson. In the final state considered, the Higgs boson decays to a bottom quark and antiquark, and the Z boson decays either into a pair of electrons, muons, or neutrinos. The analysis is (...)

[hal-02073514] An embedding technique to determine $\tau\tau$ backgrounds in proton-proton collision data

21 mars 2019

An embedding technique is presented to estimate standard model $\tau\tau$ backgrounds from data with minimal simulation input. In the data, the muons are removed from reconstructed $\mu\mu$ events and replaced with simulated tau leptons with the same kinematic properties. In this way a set of (...)

[hal-02073962] Relative particle yield fluctuations in Pb-Pb collisions at ${\mathbf{\sqrt{s_{\rm NN}}=2.76}}$ TeV

21 mars 2019

First results on $\hbox K/\pi $ , $\hbox p/\pi $ and K/p fluctuations are obtained with the ALICE detector at the CERN LHC as a function of centrality in $\text Pb--Pb $ collisions at $\sqrts_\mathrmNN =2.76\hbox TeV$ . The observable $\nu _\mathrmdyn$ , which is defined in terms of the (...)

[hal-02073540] A next-generation LHC heavy-ion experiment

21 mars 2019

The present document discusses plans for a compact, next-generation multi-purpose detector at the LHC as a follow-up to the present ALICE experiment. The aim is to build a nearly massless barrel detector consisting of truly cylindrical layers based on curved wafer-scale ultra-thin silicon (...)

[hal-02073531] Monte-Carlo simulation of positronium laser excitation and anti-hydrogen formation via charge exchange

21 mars 2019

The AEgIS experiment aims at producing antihydrogen (and eventually measuring the effects of the Earth gravitational field on it) with a method based on the charge exchange reaction between antiproton and Rydberg positronium. To be precise, antiprotons are delivered by the CERN Antiproton (...)

[hal-02073515] Searches for low-mass neutral Higgs bosons using the CMS detector

21 mars 2019

A summary of the searches performed by the CMS experiment on t he 8 TeV LHC data for direct production of additional scalars and pseudo-scalar neutra l bosons with masses below the higgs boson h 125 is presented. These searches are motivated by the predictio ns of several BSM theories, most (...)

[hal-02073513] Search for Vector Like Quarks by CMS

21 mars 2019

We present results of searches for massive vector-like top and bottom quark partners using proton-proton collision data collected with the CMS detector at the CERN LHC at a center-of-mass energy of 13 TeV. Single and pair production of vector-like quarks are studied, with decays into a variety (...)

[hal-02073517] Search for low mass Higgs-boson like resonances at CMS

21 mars 2019

A search is performed on the 8 TeV LHC data for additional scalars and pseudoscalar with masses below the newly discovered higgs boson h(125). These searches are motivated within several BSM theories, most significantly extensions of the non mininal extensions of the MSSM like the NMSSM, where (...)

[hal-02073499] Investigations of anisotropic flow using multi-particle azimuthal correlations in pp, p-Pb, Xe-Xe, and Pb-Pb collisions at the LHC

20 mars 2019

Measurements of anisotropic flow coefficients ($v_n$) and their cross-correlations using two- and multi-particle cumulant methods are reported in collisions of pp at $\sqrts = 13$ TeV, p-Pb at $\sqrts__\rm NN = 5.02$ TeV, Xe-Xe at $\sqrts__\rm NN = 5.44$ TeV, and Pb-Pb at $\sqrts__\rm NN = (...)
