This Report summarizes the results of the activities in 2014 of the Standard Model Working Group within the workshop What Next of INFN. We present a framework, general questions, and some indications of possible answers on the main issue for Standard Model physics in the LHC era and in view of possible future accelerators.
Discoveries at the LHC will soon set the physics agenda for future colliders. This report of a CERN Theory Institute includes the summaries of Working Groups that reviewed the physics goals and prospects of LHC running with 10 to 300/fb of integrated
A precise measurement of the Higgs $h to Z gamma$ decay is very challenging at the LHC, due to the very low %SM $h to Z gamma, (Z to ell ell)$ branching fraction and the shortage of kinematic handles to suppress the large SM $Z gamma$ background. We
We consider the fully constrained version of the next-to-minimal supersymmetric extension of the standard model (cNMSSM) in which a singlet Higgs superfield is added to the two doublets that are present in the minimal extension (MSSM). Assuming unive
The next-to-minimal supersymmetric standard model predicts the formation of domain walls due to the spontaneous breaking of the discrete $Z_3$-symmetry at the electroweak phase transition, and they collapse before the epoch of big bang nucleosynthesi
