Likelihood analysis of the sub-GUT MSSM in light of LHC 13-TeV data

et al. 2018

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 in below the supersymmetric grand unification scale M GUT , as can occur in mirage mediation and other models. In addition to M in , such 'sub-GUT' models have the 4 parameters of the CMSSM, namely a common gaugino mass m 1/2 , a common soft supersymmetrybreaking scalar mass m 0 , a common trilinear mixing parameter A and the ratio of MSSM Higgs vevs tan β, assuming that the Higgs mixing parameter μ > 0. We take into account constraints on strongly-and electroweakly-interacting sparticles from ∼ 36/fb of LHC data at 13 TeV and the LUX and 2017 PICO, XENON1T and PandaX-II searches for dark matter scattering, in addition to the previous LHC and dark matter constraints as well as full sets of flavour and electroweak constraints. We find a preference for M in ∼ 10 5 to 10 9 GeV, with M in ∼ M GUT disfavoured by χ 2 ∼ 3 due to the BR(B s,d → μ + μ − ) constraint. The lower limits on strongly-interacting sparticles are largely determined by LHC searches, and similar to those in the CMSSM. We find a preference for the LSP to be a Bino or Higgsino with mχ0 1 ∼ 1 TeV, with annihilation via heavy Higgs bosons a e-mail: j.costa15@imperial.ac.uk H/A and stop coannihilation, or chargino coannihilation, bringing the cold dark matter density into the cosmological range. We find that spin-independent dark matter scattering is likely to be within reach of the planned LUX-Zeplin and XENONnT experiments. We probe the impact of the (g − 2) μ constraint, finding similar results whether or not it is included.

“…Given direct knowledge of γ or N q , one can derive the absolute EEE ( e ) value using the measured anticorrelation between N γ,ob and N e,ob . This method has been attempted by both LUX [2] and XENON1T [36], but the obtained EEE values are subject to uncertainties in the N q . The measurements presented in this work were made with the XeNu apparatus, a prototype dual-phase TPC optimized for measuring low-energy ionization signals.…”

Dual-phase xenon detectors are widely used in dark matter direct detection experiments, and have demonstrated the highest sensitivities to a variety of dark matter interactions. However, a key component of the dual-phase detector technology-the efficiency of charge extraction from liquid xenon into gas-has not been well characterized. In this paper, we report a new measurement of the electron extraction efficiency (EEE) in a small xenon detector using two mono-energetic decay features of 37 Ar. By achieving stable operation at very high voltages, we measured the EEE values at the highest extraction electric field strength reported to date. For the first time, an apparent saturation of the EEE is observed over a large range of electric field; between 7.5 kV/cm and 10.4 kV/cm extraction field in the liquid xenon the EEE stays stable at the level of 1%(kV/cm) −1 . In the context of electron transport models developed for xenon, we discuss how the observed saturation may help calibrate this relative EEE measurement to the absolute EEE values. In addition, we present the implications of this result not only to current and future xenon-based dark matter searches, but also to xenon-based searches for coherent elastic neutrino-nucleus scatters.

“…In the latter case, light DM particles are searched for by looking at invisible Higgs decays and other missing transverse energy signatures, making the two types of searches highly complementary. In particular, the constraints from the LHC that can be derived on the mass of the DM particle and its couplings to the Higgs boson from the invisible Higgs decay rate, can be directly compared to the limits on the elastic scattering cross section of the DM with nuclei, obtained in a direct detection experiment such as XENON1T [17]. The ATLAS and CMS collaborations have interpreted their analyses of the invisible decays of the Higgs boson, in this framework since Refs.…”

The Higgs-portal for vector dark matter and the effective field theory approach: A reappraisal

2020

We reanalyze the effective field theory approach for the scenario in which the particles that account for the dark matter (DM) in the universe are vector states that interact only or mainly through the Standard Model-like Higgs boson observed at the LHC. This model-independent and simple approach, with a minimal set of new input parameters, is widely used as a benchmark in DM searches and studies in astroparticle and collider physics. We show that this effective theory could be the limiting case of ultraviolet complete models, taking as an example the one based on a spontaneously broken U(1) gauge symmetry that incorporates a dark gauge boson and an additional scalar that mixes with the standard Higgs boson. Hence, despite the presence of the new degrees of freedom, measurements of the invisible decay branching ratio of the Higgs boson, as performed at colliders such as the CERN LHC, can be interpreted consistently in such an effective framework and can be made complementary to results of DM searches in direct detection experiments.Particle physics proposes a compelling solution to the puzzle of the missing or dark matter (DM) in the Universe, in terms of a colorless and electrically neutral weakly interacting massive particle (WIMP) that is stable at cosmological times and has a mass in the vicinity of the electroweak scale. Such WIMPs are predicted in many extensions of the Standard Model (SM); for reviews, see Refs. [1,2] for instance. A very interesting class of such models is the one in which the DM states interact only through their couplings with the Higgs sector of the theory, the so-called Higgs-portal DM models; see Ref.[3] for a recent review. The observed cosmological relic abundance would be induced when pairs of DM states annihilate into SM fermions and gauge bosons, through the s-channel exchange of the Higgs bosons, and the latter will in turn be the mediators of the mechanisms that allow for the experimental detection of the DM states.The simplest of the Higgs-portal scenarios is when the Higgs sector is minimal and, thus, identical to the SM one, namely a single doublet Higgs field structure that leads to the unique H boson observed so far [4,5]. One could then minimally extend the model by simply adding one new particle, the DM state, as an isosinglet under the electroweak group. Nevertheless, the DM particle can have the three possible spin assignments and be a scalar, a vector or a Dirac or Majorana spin-1 2 fermion. Although only effective, this approach can be adopted as it is rather model-independent and does not make any assumption on the very nature of the DM [6-15]. Furthermore, it bears the advantage of having a very restricted number of extra parameters in addition to the SM ones [16], namely the mass of the DM particle and its coupling to the Higgs boson.Such a minimal scheme has been investigated extensively and has been probed in direct and indirect detection in astrophysical experiments, and at colliders such as the CERN LHC. In the latter case, light DM particles are searched for...
