Discovery reach for generic supersymmetry at the LHC: MT2 versus missing transverse momentum selections for pMSSM searches
B. C. Allanach, A. J. Barr, A. Dafinca +1
Different search strategies for supersymmetry have been employed by the LHC general-purpose experiments using early data. As proven by their early results, these strategies are pro…
A Supersymmetric One Higgs Doublet Model
Rhys Davies, John March-Russell, Matthew McCullough
We present a supersymmetric extension of the Standard Model in which only one electroweak doublet acquires a vacuum expectation value and gives mass to Standard Model fermions. As…
Discrete R symmetries for the MSSM and its singlet extensions
Hyun Min Lee, Stuart Raby, Michael Ratz +4
We determine the anomaly free discrete R symmetries, consistent with the MSSM, that commute with SU(5) and suppress the parameter and nucleon decay. We show that the order M of…
Vacuum stability and the Cholesky decomposition
James Unwin
We discuss how the Cholesky decomposition may be used to ascertain whether a critical point of the field theory scalar potential provides a stable vacuum configuration. We then use…
The PDF4LHC Working Group Interim Recommendations
Michiel Botje, Jon Butterworth, Amanda Cooper-Sarkar +8
This note provides an interim summary of the current recommendations of the PDF4LHC working group for the use of parton distribution functions (PDFs) and of PDF uncertainties at th…
