The double differential cross sections of the Drell-Yan lepton pair ($\ell^+\ell^-$, dielectron or dimuon) production are measured as functions invariant mass $m_{\ell\ell}$, transverse momentum $p_\mathrm{T}(\ell\ell)$, and $\phi^*_\eta$. $\phi^*_\eta$ observable, derived from angular measurements leptons highly correlated with is used to probe low-$p_\mathrm{T}(\ell\ell)$ region in a complementary way. Dilepton masses up 1 TeV investigated. Additionally, measurement performed requiring at...
The structure of nucleons is multidimensional and depends on the transverse momenta, spatial geometry, polarization constituent partons. Such a can be studied using high-energy photons produced in ultraperipheral heavy-ion collisions. first measurement azimuthal angular correlations exclusively events with two jets photon-lead interactions at large momentum transfer presented, process that considered to sensitive underlying nuclear gluon polarization. This study uses data sample lead-lead...
The first measurements of the Fourier coefficients ($V_{n\Delta}$) azimuthal distributions charged hadrons emitted from photon-proton ($\gamma$p) interactions at LHC are presented. data extracted 68.8 nb$^{-1}$ ultra-peripheral proton-lead (pPb) collisions $\sqrt{s_\mathrm{NN}}$ = 8.16 TeV using CMS detector. high energy lead ions produce a flux photons that can interact with oncoming proton. This $\gamma$p system provides set unique initial conditions multiplicity lower than in photon-lead...
The SoLid experiment aims to measure neutrino oscillation at a baseline of 6.4 m from the BR2 nuclear reactor in Belgium. Anti-neutrinos interact via inverse beta decay (IBD), resulting positron and neutron signal that are correlated time space. detector operates surface building, with modest shielding, relies on extremely efficient online rejection backgrounds order identify these interactions. A novel design has been developed using 12800 5 cm cubes for high segmentation. Each cube is...
During normal data taking CMS expects to support potentially as many 2000 analysis users. Since the beginning of 2008 there have been more than 800 individuals who submitted a remote job computing infrastructure. The bulk these users will be supported at over 40 Tier-2 centres. Supporting globally distributed community on set clusters is task that requires reconsidering methods user for Analysis Operations. In formed an Support Task Force in preparation large-scale physics activities. charge...
Sterile neutrinos have been considered as a possible explanation for the recent reactor and Gallium anomalies arising from reanalysis of flux calibration data previous neutrino experiments. A way to test this hypothesis is look distortions anti-neutrino energy caused by oscillation active sterile at close stand-off (∼6–8m) compact core. Due low rate interactions main challenge in such measurement control high level gamma rays neutron background. The SoLid experiment proposal search...
A search for exclusive two-photon production via photon exchange in proton-proton collisions, pp $\to$ p$γγ$p with intact protons, is presented. The data correspond to an integrated luminosity of 9.4 fb$^{-1}$ collected 2016 using the CMS and TOTEM detectors at a center-of-mass energy 13 TeV LHC. Events are selected diphoton invariant mass above 350 GeV both protons final state, reduce backgrounds from strong interactions. events interest those where rapidity calculated momentum losses...
A measurement is presented of the production $Z$ bosons that decay into two electrons or muons in association with jets, proton-proton collisions at a center-of-mass energy 13 TeV. The data were recorded by CMS Collaboration LHC an integrated luminosity $35.9\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$. differential cross sections are measured as function transverse momentum (${p}_{\mathrm{T}}$) boson and rapidities five jets largest ${p}_{\mathrm{T}}$. jet multiplicity distribution for...
For the first time at LHC energies, forward rapidity gap spectra from proton-lead collisions for both proton and lead dissociation processes are presented. The analysis is performed over 10.4 units of pseudorapidity a center-of-mass energy per nucleon pair sNN=8.16 TeV, almost 300 times higher than in previous measurements diffractive production proton-nucleus collisions. processes, which correspond to pomeron-lead event topology, epos-lhc generator predictions factor 2 below data, but model...
A bstract We are in an era of precision measurements at the Large Hadron Collider. The that can be achieved on some those is limited however due to large systematic uncertainties. This paper introduces a new technique reduce total uncertainty by quantifying impact single events and correlating it with event observables identify classes more sensitive effects. proof concept presented means simplified top quark mass estimator applied simulated events. Even without thorough optimization, shown...
Results are presented from a search for charged-lepton flavor violating (CLFV) interactions in top quark production and decay pp collisions at center-of-mass energy of 13 TeV. The events required to contain one oppositely charged electron-muon pair the final state, along with least jet identified as originating bottom quark. data correspond an integrated luminosity 138 fb$^{-1}$, collected by CMS experiment LHC. This analysis includes both (q $\to$ e$\mu$t) (t e$\mu$q) modes through CLFV...
