 Measurement of top quark properties in single top production / Tiko, Andres (NICPB, Tallinn) /CMS Collaboration Single top topologies are exploited for studies of top quark properties. This includes the first measurement of single top polarization in the t-channel production mode in pp collisions, which directly confirms the V-A nature of the tWb production vertex.

 Search for a low-mass pseudoscalar Higgs boson produced in association with a pair of b-quarks and decaying to tau leptons at CMS / Caillol, Cecile (Brussels U.) /CMS Collaboration A search is reported for a light pseudoscalar A boson decaying to a pair of tau leptons, produced in association with a pair of b quarks, in the context of two-Higgs-doublet models. The results are based on pp collision data at a centre-of-mass energy of s = sqrt(8) TeV accumulated by the CMS experiment at the LHC and corresponding to an integrated luminosity of 19.7 fb$^{-1}$.
