Interplay of the LHC and non-LHC dark matter searches in the effective field theory approach
(2019-01-01)
We present accurate and up-to-date constraints on the complete set of dimension five and six operators with scalar, fermion and vector dark matter (DM). We find limits using LHC monojet data, spin independent and spin ...
Detecting new physics in rare top decays at the LHC
(American Physical Society, 2014-11)
In the companion paper it was shown that there are six observables in gg → t t → bbc bℓ ν that can be used to reveal the presence of new physics (NP) in t → bbc. In the present paper we examine the prospects for detecting ...
Discovery potential for supersymmetry at a high luminosity upgrade of LHC14
(AMER PHYSICAL SOCCOLLEGE PK, 2013-08-02)
After completion of the LHC8 run in 2012, the plan is to upgrade the LHC for operation close to its design energy root s = 14 TeV, with a goal of collecting hundreds of fb(-1) of integrated luminosity. The time is propitious ...
On new physics searches with multidimensional differential shapes
(2018-03-10)
In the context of upcoming new physics searches at the LHC, we investigate the impact of multidimensional differential rates in typical LHC analyses. We discuss the properties of shape information, and argue that ...
Shedding light on the tt¯ asymmetry: the photon handle
(Springer, 2014-04)
We investigate a charge asymmetry in tt¯γtt¯γ production at the LHC that provides complementary information to the measured asymmetries in tt¯tt¯ production. We estimate the experimental uncertainty in its measurement at ...
Wh plus missing-E-T signature from gaugino pair production at the LHC
(AMER PHYSICAL SOCCOLLEGE PK, 2012)
In SUSY models with heavy squarks and gaugino mass unification, the gaugino pair production reaction pp -> (W) over tilde (+/-)(1)(Z) over tilde (2) dominates gluino pair production for m (g) over tilde less than or ...
Graviton resonance phenomenology and a pseudo-Nambu-Goldstone boson Higgs at the LHC
(American Physical Society, 2017-06-01)
We present an effective description of a spin two massive state and a pseudo-Nambu-Goldstone boson Higgs in a two site model. Using this framework, we model the spin-two state as a massive graviton and we study its ...
Slim SUSY
(Elsevier Science, 2013-04)
he new SM-like Higgs boson discovered recently at the LHC, with mass mh≃125GeV, as well as the direct LHC bounds on the mass of superpartners, which are entering into the TeV range, suggest that the minimal surviving ...
DESCRIPTION OF (PSEUDO-)RAPIDITY DENSITY AND TRANSVERSE MOMENTUM DISTRIBUTIONS IN A WIDE ENERGY RANGE (root s=22.4-7000 GeV)

Extending SUSY reach at the CERN large hadron collider using b-tagging
(Sociedade Brasileira de Física, 2007-07-01)
We analyze the potential of the CERN Large Hadron Collider on the reach of the focus point (FP) region in the mSUGRA parameter space. This region, consistent with WMAP results, is characterized by multi-TeV masses for the ...
