One of the simplest viable models for dark matter is an additional neutral scalar, stabilised by a Z2 symmetry. Using GAMBIT package and combining results from four independent samplers, we present Bayesian frequentist global fits this model. We vary singlet mass coupling along with 13 nuisance parameters, including nuclear uncertainties relevant direct detection, local density, selected quark masses couplings. include relic density measured Planck, searches LUX, PandaX, SuperCDMS XENON100,...
The discovery of a Higgs particle is possible in variety search channels at the LHC. However, true identity any putative boson will, first, remain ambiguous until one has experimentally excluded other assignments quantum numbers and couplings. We quantify degree to which can discriminate standard model from ``look-alikes'' at, or close to, moment focus on fully-reconstructible golden decay mode pair $Z$ bosons four-lepton final state. Considering both on-shell off-shell $Z$'s, we show how...
We introduce recursive jigsaw reconstruction, a technique for analyzing reconstructed particle interactions in the presence of kinematic and combinatoric unknowns associated with unmeasured indistinguishable particles, respectively. By factorizing missing information according to decays rest frames intermediate an interchangeable configurable set rules, algorithms resolving these unknowns, are applied approximately reconstruct arbitrarily many their entirety. That reconstruction approach can...
The observation of light super-partners from a supersymmetric extension to the Standard Model is an intensely sought-after experimental outcome, providing explanation for stabilization electroweak scale and indicating existence new particles which could be consistent with dark matter phenomenology. For compressed scenarios, where sparticle spectra mass-splittings are small decay products carry low momenta, dedicated techniques required in all searches supersymmetry. In this paper we suggest...
At the LHC, many new physics signatures feature pair-production of massive particles with subsequent direct or cascading decays to weakly-interacting particles, such as SUSY scenarios conserved R-parity $H \to W(\ell\nu)W(\ell\nu)$. We present a set dimension-less variables that can assist early discovery processes this type in conjunction mass dimension will expedite characterization these processes.
In Ref. (GAMBIT Collaboration: Athron et. al., Eur. Phys. J. C. arXiv:1705.07908 , 2017) we introduced the global-fitting framework GAMBIT. this addendum, describe a new minor version increment of package. GAMBIT 1.1 includes full support for Mathematica backends, which in some detail here. As an example, backend SUSYHD (Vega and Villadoro, JHEP 07:159, 2015), calculates mass Higgs boson MSSM from effective field theory. We also updated likelihoods PrecisionBit DarkBit, decay data included DecayBit.
A bstract long-standing kinematic challenge in data analysis at hadron colliders is the determination of masses invisible particles. This issue particularly relevant searches for evidence dark matter production, which remains one prominent targets future collider experiments. In this paper, we show that additional information from precision timing measurements, provided by planned detector upgrades during high- luminosity run LHC (HL-LHC), allows previously unrealizable measurements particle...
We present the preparatory work for measurement of W + jets / Z ratio and use sample as a “candle physics detector commissioning with first LHC data at CMS. The studies target early understanding production LHC. They provide handles data-driven extraction Standard Model backgrounds to New Physics searches, direct probe benchmark testing relevant QCD calculations.
