Studies of Charm Quark Diffusion inside Jets Using Pb-Pb and pp Collisions at sqrt[s_{NN}]=5.02 TeV.

The first study of charm quark diffusion with respect to the jet axis in heavy ion collisions is presented. The measurement is performed using jets with p_{T}^{jet}>60  GeV/c and D^{0} mesons with p_{T}^{D}>4  GeV/c in lead-lead (Pb-Pb) and proton-proton (pp) collisions at a nucleon-nucleon center-of-mass energy of sqrt[s_{NN}]=5.02  TeV, recorded by the CMS detector at the LHC.

Azimuthal separation in nearly back-to-back jet topologies in inclusive 2- and 3-jet events in collisions at .

A measurement for inclusive 2- and 3-jet events of the azimuthal correlation between the two jets with the largest transverse momenta, , is presented. The measurement considers events where the two leading jets are nearly collinear ("back-to-back") in the transverse plane and is performed for several ranges of the leading jet transverse momentum. Proton-proton collision data collected with the CMS experiment at a center-of-mass energy of and corresponding to an integrated luminosity of are used.

Measurement of exclusive photoproduction in ultraperipheral pPb collisions at .

Exclusive photoproduction is measured for the first time in ultraperipheral pPb collisions at with the CMS detector. The cross section is b at for photon-proton centre-of-mass energies between 29 and . The differential cross section is measured in the interval as a function of , where is the squared four-momentum transfer at the proton vertex.

Search for a heavy pseudoscalar boson decaying to a Z and a Higgs boson at .

A search is presented for a heavy pseudoscalar boson decaying to a Z  boson and a Higgs boson with mass of 125 . 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 performed using a data sample corresponding to an integrated luminosity of 35.

Studies of Beauty Suppression via Nonprompt D^{0} Mesons in Pb-Pb Collisions at sqrt[s_{NN}]=5.02 TeV.

The transverse momentum spectra of D^{0} mesons from b hadron decays are measured at midrapidity (|y|<1) in pp and Pb-Pb collisions at a nucleon-nucleon center of mass energy of 5.02 TeV with the CMS detector at the LHC. The D^{0} mesons from b hadron decays are distinguished from prompt D^{0} mesons by their decay topologies.
