The differential cross sections of $\Lambda_\mathrm{c}^+$ baryon production are measured via the exclusive decay channel $\to$ pK$^-\pi^+$ using CMS detector at LHC. Spectra as a function transverse momentum ($p_\mathrm{T}$) in proton-proton (pp) and lead-lead (PbPb) collisions nucleon-nucleon center-of-mass energy 5.02 TeV. measurement is performed within rapidity interval $|y|$ $<$ 1.0 $p_\mathrm{T}$ range 5-20 GeV/$c$ pp 10-20 PbPb collisions. observed yields for suggest possible...
The transverse momentum spectra of D^{0} mesons from b hadron decays are measured at midrapidity (|y|<1) in pp and Pb-Pb collisions a nucleon-nucleon center mass energy 5.02 TeV with the CMS detector LHC. distinguished prompt by their decay topologies. In collisions, B→D^{0} yield is found to be suppressed p_{T} range 2 100 GeV/c as compared collisions. suppression weaker than that charged hadrons for around 10 GeV/c. While theoretical calculations incorporating partonic loss quark-gluon...
A search for decays of the Higgs and Z boson to pairs J/$\psi$ or $\Upsilon$(nS) (n = 1, 2, 3) mesons, with their subsequent decay $\mu^+\mu^-$ pairs, is presented. The analysis uses data from proton-proton collisions at $\sqrt{s} =$ 13 TeV, collected CMS detector LHC in 2017 corresponding an integrated luminosity 37.5 fb$^{-1}$. While observation such a this sample would indicate presence physics beyond standard model, no significant excess observed. Upper limits 95% confidence level are...
The second- and third-order azimuthal anisotropy Fourier harmonics of charged particles produced in $\text{pPb}$ collisions, at $\sqrt{{s}_{NN}}=8.16\phantom{\rule{0.16em}{0ex}}\text{TeV}$, are studied over a wide range event multiplicities. Multiparticle correlations used to isolate global properties stemming from the collision overlap geometry. second-order ``elliptic'' harmonic moment is obtained with high precision through four-, six-, eight-particle and, for first time, ``triangular''...
In 2017 a new pixel detector was installed in the CMS detector. This so-called Phase-1 features four barrel layers central region and three disks per end forward regions. The upgraded requires an data acquisition (DAQ) system to accept format larger event sizes. A DAQ control has been developed based on combination of custom commercial microTCA parts. Custom mezzanine cards standard carrier provide front-end driver for readout, two types controller configuration distribution clock trigger...
Previous CMS measurements have demonstrated the collective nature of multiparticle correlations in high-multiplicity pPb collisions at LHC. This collectivity is consistent with a hydrodynamic flow origin. However, it can also be interpreted terms initial state effects arising from gluon saturation. The pseudorapidity dependence azimuthal Fourier coefficients (vn) expected to sensitive underlying mechanism with, picture, longer lifetime fireball on Pb-going side lead larger signal than found...
Studies of azimuthal anisotropies for very high pT particles in relativistic heavy ion collisions provide crucial information on the path length dependence parton energy loss mechanism quark-gluon plasma. Final high-precision data elliptic (v2) and triangular (v3) anisotropy harmonics charged particles, obtained with scalar product method, are presented up to pT∼100 GeV/c PbPb at sNN=5.02 TeV, using recorded during LHC run 2 CMS detector. In particular, v3 harmonic is explored a regime first...
The elliptic and higher-order azimuthal anisotropy Fourier harmonics (vn) are obtained for pPb collisions at sNN=8.16TeV over a wide range of event multiplicities based on multiparticle correlations. data were collected by the CMS experiment during 2016 LHC run. A sample peripheral PbPb sNN=5.02TeV covering similar to results is also analyzed comparison. ratios different harmonic moments both v2 v3 with high precision, which allows direct comparison theoretical predictions assuming...
