Top quark properties and single top at CMS / Skovpen, Kirill (Strasbourg, IPHC) /CMS Collaboration
Measurements of top-quark properties as well as single top-quark production are presented, obtained from the CMS data collected in 2011 and 2012 at centre-of-mass energies of 7 and 8 TeV. The results include measurements of the top pair charge asymmetry, the W helicity in top decays, the ttbar spin correlation and the search for anomalous couplings. [...]

Studies of vector boson production at CMS / Dordevic, Milos (CERN) /CMS Collaboration
The most recent diboson production and electroweak physics results from CMS are presented. This overview is focused on the precise measurement of WW, WZ, ZZ and $\gamma\gamma$ production, as well as W or Z production in association with a photon. [...]

Electroweak production and hadronic activity in $Zjj$ events at CMS / Cornelis, Tom (Antwerp U.) /CMS Collaboration
The measurement of the electroweak production cross section of a $Z$ boson in association with two jets in proton-proton collisions at $\sqrt{s} = 8$ TeV is presented. The results are based on a data sample recorded by the CMS experiment with an integrated luminosity of 19.7 fb$^{-1}$. [...]

Searches for Supersymmetry at CMS / Autermann, Christian (Aachen, Tech. Hochsch.) /CMS Collaboration
CMS has searched for supersymmetry using the full dataset recorded until the end of 2012, at a center-of-mass energy of 8 TeV corresponding to an integrated luminosity of 20 fb-1. The observations are consistent with the expectations from the standard model. [...]

Searches for extra dimensions with CMS / Shmatov, Sergey (Dubna, JINR) /CMS Collaboration
During 2012, the CMS Collaborations at the Large Hadron Collider collected approximately 20 fb-1 of pp collision data with a center-of-mass energy of 8 TeV. The results of searches for Extra Dimensions will be discussed in this talk.(paper in Russian)

Production of leading charged particles and leading charged-particle jets at small transverse momenta with the CMS detector / Knutsson, Albert Hans (Antwerp U.) /CMS Collaboration
In this talk we discuss recent measurements of integrated leading minijet cross sections in pp collisions at 8 TeV performed with the CMS detector. The minijet cross sections are sensitive to the unitarity bound set by the total inelastic cross section. [...]

Measurement of the underlying event activity using charged particle jets in proton-proton collisions at 2.76 TeV / Wang, Wei Yang (Singapore Natl. U.) /CMS Collaboration
A measurement of the underlying event activity is performed in proton-proton collisionsat sqrt(s)=2.76 GeV, using data collected by the CMS experiment at the LHC.The average multiplicity and scalar-pT sum densities of charged particles in the azimuthalregion transverse to the leading charged particle jet at central pseudorapidities are studied.A steep rise of the underlying event activity is seen with increasing leading jet pTup to a few GeV/c, above which a slower rate of increase is observed. Bydividing the transverse region into the minimum and maximum activity ones on eachside of the leading jet, further information on the dynamic of the UE is obtained. [...]
