 Searches for high mass resonances in dilepton and diphoton final states / Charaf, Otman (Alabama U.) /ATLAS and CMS Collaborations The search for new physics at the TeV scale is one of the major aspects of the ATLAS and CMS experimental programmes. This includes a myriad of theoretical models involving resonances that can can decay to leptons or photons. [...] CMS-CR-2015-374.- Geneva : CERN, 2015 - 10 p.

 Searches for heavy stable charged particles and other exotic signatures with large ionization at the LHC / Kazana, Malgorzata (NCBJ, Swierk) /ATLAS and CMS Collaborations The signature of the large ionization is used to search for signals of heavy stable charged particles or other new particles foreseen by models beyond the Standard Model. The related searches in proton-proton collisions at the Large Hadron Collider (LHC) are reviewed. [...] CMS-CR-2016-003.- Geneva : CERN, 2016 - 7 p.

 Particle Spectra in Minimum Bias events at 13 TeV / Grados Luyando, Juan Manuel (DESY) /CMS Collaboration Measurements of particle spectra at 13 TeV are presented for different event topologies..

 CMS Underlying Event and Double Parton Scattering Monte Carlo Tunes / Sunar Cerci, Deniz (Cukurova U.) /CMS Collaboration Three new PYTHIA 8 underlying event (UE) tunes are presented, one using the CTEQ6L1 parton distribution function (PDF), one using HERAPDF1.5LO, and one using the NNPDF2.3LO PDF; two new PYTHIA 6 UE tunes, one for the CTEQ6L1 PDF and one for the HERAPDF1.5LO, and one new HERWIG++ UE tune for the CTEQ6L1 PDF are also available. Simultaneous fits to CDF UE data at center-of-mass energies of 0.3, 0.9, and 1.96 TeV, together with CMS UE data at 7 TeV, check the UE models and constrain their parameters, providing thereby more precise predictions for proton-proton collisions at 13 TeV.

 MPI and UE corrections to jet measurements and influence on PDF determination and $\alpha_s$ / Cerci, Salim (Cukurova U.) /CMS Collaboration The UE and MPI contributions and corrections to jet measurements will be presented, as well as an estimate on the uncertainties. In addition, the influence from initial and final state parton shower will be discussed.. CMS-CR-2016-020.- Geneva : CERN, 2016 - 5 p.

 Multi-jet measurements at CMS / Safronov, Grigory (Moscow, ITEP) /CMS Collaboration The cross section of hadronic jet production gives direct access to the basic QCD components like the strong coupling constant, $\alpha_s$, or the parton density functions. Measurements of correlations between jets allow to test pQCD resummation procedures or parton shower models. [...] CMS-CR-2016-023.- Geneva : CERN, 2016 - 8 p.

 ATLAS/CMS Probing PDFs and soft QCD at the LHC / Safronov, Grigory (Moscow, ITEP) /ATLAS and CMS Collaborations LHC has delivered 30 fb$^{-1}$ of proton-proton collisions at center-of-mass energies of 7 and 8 TeV in 2010-2012 during the LHC Run I. Run II has started in 2015 and approximately 200 pb$^{-1}$ of proton-proton collisions at $\sqrt{s}=13$ TeV have been delivered by September. [...] CMS-CR-2015-378.- Geneva : CERN, 2015 - 12 p.

 Neutrino physics with the SHiP experiment / Buonaura, Annarita (Universita e INFN, Napoli (IT)) /SHiP Collaboration Despite the Standard Model (SM) has been strongly confirmed by the Higgs discovery, several experimental facts are still not explained. The SHiP experiment (Search for Hidden Particles), a beam dump experiment at CERN, aims at the observation of long lived particles very weakly coupled with ordinary matter.
