We discuss quantum entanglement and violation of Bell inequalities in the $H\rightarrow ZZ$ decay, particular when two $Z-$bosons decay into light leptons. Although such process implies an important suppression statistics, this is traded by clean signals from a "quasi maximally-entangled" system, which makes it very promising to check these crucial phenomena at high energy. In paper we devise novel framework extract $H \to data all significant information related goal, spin correlation...
A real singlet scalar, connected to the Standard Model sector through a portal with Higgs boson, is one of simplest and most popular models for dark matter (DM). However, experimental advances in direct indirect DM searches, together latest results from LHC, have ruled out vast areas parameter space this scenario; are expected probe it completely within next years, ruling if no signal found. Motivated by simplicity model, article we address minimal, renormalizable extension that could evade...
One of the most exciting explanations advanced for recent diphoton excess found by ATLAS and CMS is in terms sgoldstino decays: a signal low-energy supersymmetry-breaking scenarios. The sgoldstino, scalar, couples directly to gluons photons, with strength related gaugino masses, that can be right magnitude explain excess. However, fitting suggested resonance width, Γ≃45GeV, not so easy. In this paper we explore efficient possibilities enhance via decay into two Higgses, Higgsinos through...
We present the results obtained by "Triple Gauge Couplings" working group during LEP2 Workshop (1994-1995). The report concentrates on measurement of $WWγ$ and $WWZ$ couplings in $e^-e^+\to W^-W^+$ or, more generally, four-fermion production at LEP2. In addition detection new interactions bosonic sector via other channels is discussed.
The addition of a scalar singlet provides one the simplest extensions Standard Model. In this work we briefly review latest constraints on mass and mixing new Higgs boson study its production decay at LHC. We mainly focus double in $$ hh\to b\overline{b}WW\to b\overline{b}{\ell}^{+}\nu {\ell}^{-}\overline{\nu} channel. This is found to be efficient region masses heavy 260-500 GeV, so it complementary 4b channel, more for bosons with greater than 500 GeV. analyse di-leptonic channel detail...
The idea of "Natural SUSY", understood as a supersymmetric scenario where the fine-tuning is mild possible, reasonable guide to explore phenomenology. In this paper, we re-examine issue in context MSSM including several improvements, such mixing conditions for different soft terms and presence potential extra fine-tunings that must be combined with electroweak one. We give tables plots allow easily evaluate corresponding naturalness bounds any theoretical model defined at high-energy (HE)...
We study an extension of the Standard Model that addresses hints lepton flavour universality violation observed in $B\to K^{(*)} l^+l^-$ decays at LHCb, while providing a viable candidate for dark matter. The model incorporates two new scalar fields and Majorana fermion induce one-loop contributions to $B$ meson decays. show agreement with observational data requires couplings be complex can reproduce matter relic density. This combination cosmological constraints sets upper limit on...
We consider domain walls that appear in supersymmetric QCD with Nf < Nc massive flavours. In particular, for 2 we explicitly construct the interpolate between vacua labeled by i and (i+ N_f). show these solutions are Bogomol'nyi-Prasad-Sommerfield (BPS) saturated any value of mass matter fields. This fact allows us to evaluate large limit walls. comment on relevance gluodynamics.
