A facility to search for hidden particles at the CERN SPS: the SHiP physics case.

Sergey Alekhin, +95 more
TL;DR: It is demonstrated that the SHiP experiment has a unique potential to discover new physics and can directly probe a number of solutions of beyond the standard model puzzles, such as neutrino masses, baryon asymmetry of the Universe, dark matter, and inflation.

HiggsBounds-4: improved tests of extended Higgs sectors against exclusion bounds from LEP, the Tevatron and the LHC

TL;DR: HiggsBounds as mentioned in this paper is a tool to test models with arbitrary Higgs sectors, containing both neutral and charged Higgs bosons, against the published exclusion bounds from Higgs searches at the LEP, Tevatron and LHC experiments.

New constraints on the charged Higgs sector in two-Higgs-doublet models.

TL;DR: This analysis systematically takes account of theoretical uncertainties in bag factors, decay constants, and quark mixing matrix elements by Monte Carlo sampling to determine the regions in the charged-Higgs-boson parameter space that are consistent with present data.

The Fermion Mass Scale and Possible Effects of Higgs Bosons on Experimental Observables

TL;DR: In this article, the authors considered a SU(2) @ U(1) gauge theory with two (or more) Higgs doublets, but with the fermion mass scale dctcrmined by the vacuum expectation values of the Higgs particles rather than determined only by widely differing Higgs couplings.

The b → se+e− and b → sγ decays with next-to-leading logarithmic QCD-corrections

TL;DR: In this article, the QCD-corrected effective hamiltonian for the b → se+e− and b → sγ decays is evaluated including the next-to-leading logarithmic effects which considerably weaken the qCD corrections to both decays.
