 Resurgent Analysis of Localizable Observables in Supersymmetric Gauge Theories / Aniceto, Inês ; Russo, Jorge G ; Schiappa, Ricardo Localization methods have recently led to a plethora of new exact results in supersymmetric gauge theories, as certain observables may be computed in terms of matrix integrals.

 Matching the $D^6 {\cal R}^4$ interaction at two-loops / D'Hoker, Eric ; Green, Michael B ; Pioline, Boris ; Russo, Rodolfo The coefficient of the $D^6 {\cal R}^4$ interaction in the low energy expansion of the two-loop four-graviton amplitude in type II superstring theory is known to be proportional to the integral of the Zhang-Kawazumi (ZK) invariant over the moduli space of genus-two Riemann surfaces.

 A Method to Simulate the Observed Surface Properties of Proton Irradiated Silicon Strip Sensors / Peltola, Timo Hannu Tapani (Helsinki Inst. of Phys.) /CMS Collaboration During the scheduled high luminosity upgrade of the LHC, the world's largest particle physics accelerator at CERN, the position sensitive silicon detectors installed in the vertex and tracking part of the CMS experiment will face a more intense radiation environment than the present system was designed for. To upgrade the tracker to the required performance level, extensive measurements and simulation studies have already been carried out. [...] CMS-CR-2014-247.- Geneva : CERN, 2014 - 9 p.

 Higgs Boson in Lepton Decay Modes at the CMS Experiment / Choudhury, Somnath (DESY) /CMS Collaboration The results on the standard model Higgs boson in lepton decay channels with tau pair and muon pair final states using 25 fb$^{-1}$ of pp collision data at 7 and 8 TeV center-of-mass energies collected by the CMS detector at the LHC has been summarized. A direct evidence of the Higgs-lepton coupling is established with the tau pair decay mode. [...] CMS-CR-2014-332.- Geneva : CERN, 2014 - 7 p.

 Study of Topological Distributions of Inclusive Three- and Four-jet Events at the LHC / Gupta, Ruchi (Panjab U.) /CMS Collaboration A study of inclusive topological distributions of three- and four-jet events has been conducted by the CMS Collaboration at the LHC with a data sample corresponding to an integrated luminosity of 5.05 fb$^{-1}$ at a centre of mass energy of 7 TeV. Kinematic and angular distributions in inclusive multijet final states serve as a natural probe of quantum chromodynamics and can reveal its inner dynamics.

 Search for H to bb in association with single top quarks as a test of Higgs boson couplings / Fink, Simon (Karlsruhe U., EKP) /CMS Collaboration The production of a Higgs boson in association with a single top quark is one of a few channels which are sensitive for not yet excluded anomalous couplings of the Higgs boson to fermions. Multivariate analysis tools are used for the reconstruction and classification of signal events, where the Higgs boson decays into bottom quarks and the single top quark decays leptonically.

 Searches for invisible decay modes of the Higgs boson with the CMS detector / Trocino, Daniele (Northeastern U.) /CMS Collaboration A search for Higgs boson invisible decay modes has been carried out in events where the Higgs boson is produced in association with a Z boson as well as through vector boson fusion. In the associated production search, electron, muon and b-quark pair decay modes of the Z boson are considered. [...] CMS-CR-2014-312.- Geneva : CERN, 2014 - 7 p.

 Muon reconstruction and identification in CMS Run I and towards Run II / Kratschmer, Ilse (Vienna, OAW) /CMS Collaboration The performance of the muon reconstruction and identification in the CMS experiment at the LHC has been studied on data collected in pp collisions at $\sqrt{s} =$ 7 and 8~TeV. Results from the measurements of the muon identification efficiencies, hadron misidentification probabilities as well as the muon momentum scale and resolution are presented..
