 A Theta lift representation for the Kawazumi-Zhang and Faltings invariants of genus-two Riemann surfaces / Pioline, Boris (CERN and LPTHE) The Kawazumi-Zhang invariant $\varphi$ for compact genus-two Riemann surfaces was recently shown to be a eigenmode of the Laplacian on the Siegel upper half-plane, away from the separating node.

 Analysis of events with $b$-jets and a pair of leptons of the same charge in $pp$ collisions at $\sqrt{s}=8$ TeV with the ATLAS detector An analysis is presented of events containing jets including at least one $b$-tagged jet, sizeable missing transverse momentum, and at least two leptons including a pair of the same electric charge, with the scalar sum of the jet and lepton transverse momenta being large.

 Physics potential for the measurement of sigma(H nu antinu ̄) x BR(H -->μ+μ-) at a 1.4 TeV CLIC collider / Milutinovic-Dumbelovic, Gordana (University of Belgrade (RS)) ; Bozovic-Jelisavcic, Ivanka (University of Belgrade (RS)) ; Grefe, Christian (Universitaet Bonn (DE)) ; Kacarevic, Goran (University of Belgrade (RS)) ; Lukic, Strahinja (University of Belgrade (RS)) ; Pandurovic, Mila (University of Belgrade (RS)) ; Roloff, Philipp Gerhard (CERN) ; Smiljanic, Ivan (University of Belgrade (RS)) Measurements of Higgs couplings at CLIC will offer the potential for a rich precision phys- ics programme and for the search for physics beyond the Standard Model(SM). The poten- tial for measuring the SM Higgs boson decay into two muons at a 1.4 TeV CLIC collider is addressed in this paper. [...] CLICdp-Pub-2015-001.- Geneva : CERN, 2015 - 10. Fulltext: PDF;

 Alternative Approach to the Provision of the High-field Dipole for FCC-hh / Taylor, Thomas (CERN) This paper describes a possible approach to reducing the complexity and cost of the high field dipole magnets. In addition the cooling of the winding could be improved in the proposed design, with a consequent reduction in the shielding requirements.

 Measurement of charged-particle spectra in Pb+Pb collisions at $\sqrt{{s}_\mathsf{NN}} = 2.76$TeV with the ATLAS detector at the LHC / ATLAS Collaboration Charged-particle spectra obtained in 0.15nb${}^{-1}$ of Pb+Pb interactions at $\sqrt{{s}_\mathsf{NN}}=2.76$TeV and 4.2pb${}^{-1}$ of pp interactions at $\sqrt{s}=2.76$TeV with the ATLAS detector at the LHC are presented in a wide transverse momentum ($0.5 < p_{\mathrm{T}} < 150$GeV) and pseudorapidity ($|\eta|<2$) range.

 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. [...] CMS-CR-2015-027.- Geneva : CERN, 2015 - 11 p.

 Dirac Triplet Extension of the MSSM / Alvarado, C ; Delgado, A ; Martin, A ; Ostdiek, B In this paper we explore extensions of the Minimal Supersymmetric Standard Model involving two $SU(2)_L$ triplet chiral superfields that share a superpotential Dirac mass yet only one of which couples to the Higgs fields.
