Likelihood Analysis of the Minimal AMSB Model
E. Bagnaschi, M. Borsato, K. Sakurai +17
We perform a likelihood analysis of the minimal Anomaly-Mediated Supersymmetry Breaking (mAMSB) model using constraints from cosmology and accelerator experiments. We find that a w…
The NUHM2 after LHC Run 1
O. Buchmueller, R. Cavanaugh, M. Citron +11
We make a frequentist analysis of the parameter space of the NUHM2, in which the soft supersymmetry (SUSY)-breaking contributions to the masses of the two Higgs multiplets, $m^2_{H…
Likelihood Analysis of Supersymmetric SU(5) GUTs
E. Bagnaschi, J. C. Costa, K. Sakurai +17
We perform a likelihood analysis of the constraints from accelerator experiments and astrophysical observations on supersymmetric (SUSY) models with SU(5) boundary conditions on so…
Efficiency measurements of GEM GE1/1 chambers in the upgraded CMS Endcap Muon System using 2023 collision data at TeV
M. Abbas, S. Abbott, M. Abbrescia +184
The CMS experiment at the Large Hadron Collider employs Gas Electron Multiplier (GEM) detectors, a technology based on gaseous ionization, as one of the muon detectors. The muon sp…
Sensitivity to millicharged particles in future proton-proton collisions at the LHC
A. Ball, J. Brooke, C. Campagnari +25
We report on the expected sensitivity of dedicated scintillator-based detectors at the LHC for elementary particles with charges much smaller than the electron charge. The dataset…
Search for millicharged particles in proton-proton collisions at TeV
S. Alcott, Z. Bhatti, J. Brooke +34
We report on a search for elementary particles with charges much smaller than the electron charge using a data sample of proton-proton collisions provided by the CERN Large Hadron…
Likelihood Analysis of the Sub-GUT MSSM in Light of LHC 13-TeV Data
J. C. Costa, E. Bagnaschi, K. Sakurai +13
We describe a likelihood analysis using MasterCode of variants of the MSSM in which the soft supersymmetry-breaking parameters are assumed to have universal values at some scale $M…
The End of the CMSSM Coannihilation Strip is Nigh
M. Citron, J. Ellis, F. Luo +3
A recent global fit to the CMSSM incorporating current constraints on supersymmetry, including missing transverse energy searches at the LHC, BR(B_s to mu+ mu-) and the direct XENO…
Search for millicharged particles in proton-proton collisions at TeV
A. Ball, G. Beauregard, J. Brooke +35
We report on a search for elementary particles with charges much smaller than the electron charge using a data sample of proton-proton collisions provided by the CERN Large Hadron…
Run 2 Upgrades to the CMS Level-1 Calorimeter Trigger
B. Kreis, J. Berryhill, R. Cavanaugh +61
The CMS Level-1 calorimeter trigger is being upgraded in two stages to maintain performance as the LHC increases pile-up and instantaneous luminosity in its second run. In the firs…
The CMSSM and NUHM1 in Light of 7 TeV LHC, B_s to mu+mu- and XENON100 Data
O. Buchmueller, R. Cavanaugh, M. Citron +14
We make a frequentist analysis of the parameter space of the CMSSM and NUHM1, using a Markov Chain Monte Carlo (MCMC) with 95 (221) million points to sample the CMSSM (NUHM1) param…
Physics at a 100 TeV pp collider: beyond the Standard Model phenomena
T. Golling, M. Hance, P. Harris +111
This report summarises the physics opportunities in the search and study of physics beyond the Standard Model at a 100 TeV pp collider.
The pMSSM10 after LHC Run 1
K. J. de Vries, E. A. Bagnaschi, O. Buchmueller +14
We present a frequentist analysis of the parameter space of the pMSSM10, in which the following 10 soft SUSY-breaking parameters are specified independently at the mean scalar top…
Collider Interplay for Supersymmetry, Higgs and Dark Matter
O. Buchmueller, M. Citron, J. Ellis +5
We discuss the potential impacts on the CMSSM of future LHC runs and possible electron-positron and higher-energy proton-proton colliders, considering searches for supersymmetry vi…
Likelihood Analysis of the pMSSM11 in Light of LHC 13-TeV Data
E. Bagnaschi, K. Sakurai, M. Borsato +15
We use MasterCode to perform a frequentist analysis of the constraints on a phenomenological MSSM model with 11 parameters, the pMSSM11, including constraints from ~ 36/fb of LHC d…
Supersymmetric Dark Matter after LHC Run 1
E. A. Bagnaschi, O. Buchmueller, R. Cavanaugh +13
Different mechanisms operate in various regions of the MSSM parameter space to bring the relic density of the lightest neutralino, neutralino_1, assumed here to be the LSP and thus…
