The Standard Model of particle physics contains three active neutrinos associated to three charged leptons: electron, muon and tau. Electron neutrino and muon neutrino were experimentally observed in 1956 and 1962 respectively but observation of tau neutrino was released at the beginning of 21st century as its observation requires special detection techniques. Only few measurements with limited statistics have been done in order to measure its properties. The DsTau project at CERN has been proposed to study tau neutrino production aiming precise measurement of tau neutrino production cross section. In addition, the analysis of 2.3 × 10^8 proton interactions will yield 10^5 charmed decay which will allow us to extract many more physical quantities like measurement of charmed hadron lifetime and measurement of interaction lengths of charmed hadrons. In this thesis work, the track reconstruction performance of the DsTau detector has been studied in detail and using a sub-sample of 2018 pilot run, the charmed hadron lifetimes have been obtained with the help of MC simulations. The obtained lifetimes are consistent with PDG values.

Measurement of D*(+/-) meson production in jets from pp collisions at root s=7 TeV with the ATLAS detector Aad, G.; et. al. (2012-03-19) This paper reports a measurement of D*(+/-) meson production in jets from proton- proton collisions at a center- of- mass energy of root s = 7 TeV at the CERN Large Hadron Collider. The measurement is based on a data sample recorded with the ATLAS detector with an integrated luminosity of 0.30 pb(-1) for jets with transverse momentum between 25 and 70 GeV in the pseudorapidity range vertical bar eta vertical bar D-0 pi(+), D-0 -> K-pi(+), and its charge conjugate. The production rate is found to be N(D*(+/...
Measurement of the transverse momentum distribution ofWbosons inppcollisions ats=7 TeVwith the ATLAS detector Aad, G.; et. al. (American Physical Society (APS), 2012-1-18) This paper describes a measurement of the W boson transverse momentum distribution using ATLAS pp collision data from the 2010 run of the LHC at ffiffi s p ¼ 7 TeV, corresponding to an integrated luminosity of about 31 pb 1. Events form both W ! e and W ! are used, and the transverse momentum of the W candidates is measured through the energy deposition in the calorimeter from the recoil of the W. The resulting distributions are unfolded to obtain the normalized differential cross sections as a function ...
Properties of jets measured from tracks in proton-proton collisions at center-of-mass energy root s=7 TeV with the ATLAS detector Aad, G.; et. al. (2011-09-20) Jets are identified and their properties studied in center-of-mass energy root s = 7 TeV proton-proton collisions at the Large Hadron Collider using charged particles measured by the ATLAS inner detector. Events are selected using a minimum bias trigger, allowing jets at very low transverse momentum to be observed and their characteristics in the transition to high-momentum fully perturbative jets to be studied. Jets are reconstructed using the anti-k(t) algorithm applied to charged particles with two radiu...
Study of W boson production in pPb collisions at root(NN)-N-S=5.02 TeV Adam, W.; et. al. (Elsevier BV, 2015-11-01) The first study of W boson production in pPb collisions is presented, for bosons decaying to a muon or electron, and a neutrino. The measurements are based on a data sample corresponding to an integrated luminosity of 34.6 nb(-1) at a nucleon-nucleon centre-of-mass energy of root(NN)-N-S = 5.02 TeV, collected by the CMS experiment. The W boson differential cross sections, lepton charge asymmetry, and forward-backward asymmetries are measured for leptons of transverse momentum exceeding 25 GeV/c, and as a fu...
Measurement of the W charge asymmetry in the W -> mu nu decay mode in pp collisions at root s=7 TeV with the ATLAS detector Aad, G.; et. al. (Elsevier BV, 2011-06-27) This Letter reports a measurement of the muon charge asymmetry from W bosons produced in proton-proton collisions at a centre-of-mass energy of 7 TeV with the ATLAS experiment at the LHC. The asymmetry is measured in the W -> mu nu decay mode as a function of the muon pseudorapidity using a data sample corresponding to a total integrated luminosity of 31 pb(-1). The results are compared to predictions based on next-to-leading order calculations with various parton distribution functions. This measurement pr...
