Phenomenology of Supersymmetric Large Extra Dimensions [PDF]
, 2002 We study the phenomenology of a supersymmetric bulk in the scenario of large extra dimensions. The virtual exchange of gravitino KK states in selectron pair production in polarized \epem collisions is examined. The leading order operator for this exchange is dimension six, in contrast to that of graviton KK exchange which induces a dimension eight ...

Phenomenology of Large Extra Dimensions Models at Hadrons Colliders using Monte Carlo Techniques (Spin-2 Graviton) [PDF]
, 2015 Large Extra Dimensions Models have been proposed to remove the hierarchy problem and give an explanation why the gravity is so much weaker than the other three forces. In this work, we present an analysis of Monte Carlo data events for new physics signatures of spin-2 Graviton in context of ADD model with total dimensions $D=4+ ,$ $ = 1,2,3,4,5,6 ...

Possibility of hypothetical stable micro black hole production at future 100 TeV collider
European Physical Journal C: Particles and Fields, 2017 We study the phenomenology of TeV-scale black holes predicted in theories with large extra dimensions, under the further assumption that they are absolutely stable. Our goal is to present an exhaustive analysis of safety of the proposed 100 TeV collider,

Phenomenology of Hyperbolic Large Extra Dimensions for Hadron Colliders
, 2007 The subject of extra dimensions has experienced a renewed interest in recent years. Arkani-Hamed, Dimopoulos, and Dvali (ADD) have pointed out that it is possiblethat there exist extra dimensions that are as large as micrometer sized, if theStandard Model fields are restricted to a four-dimensional brane.

Journal of High Energy Physics, 2021 In this paper we study shells of matter and black holes on the expanding bubbles realizing de Sitter space, that were proposed in [4]. We construct explicit solutions for a rigid shell of matter as well as black hole like solutions.

Journal of High Energy Physics, 2021 We present a novel algorithm to identify potential dispersed signals of new physics in the slew of published LHC results. It employs a random walk algorithm to introduce sets of new particles, dubbed “proto-models”, which are tested against simplified ...

Cosmic ray boosted sub-GeV gravitationally interacting dark matter in direct detection
Journal of High Energy Physics, 2020 Detections of non-gravitational interactions of massive dark matter (DM) with visible sector so far have given null results. The DM may communicate with the ordinary matter only through gravitational interaction.

Journal of High Energy Physics, 2021 We investigate a two Higgs doublet model with extra flavour depending U(1) X gauge symmetry where Z′ boson interactions can explain the Atomki anomaly by choosing appropriate charge assignment for the SM fermions.

Resummed inclusive cross-section in ADD model at N3LL
Journal of High Energy Physics, 2020 We present three loop soft-plus-virtual (SV) corrections to the spin-2 production at the Large Hadron Collider (LHC). For this calculation, we make use of the recently computed quark and gluon three loop form factors for the spin-2 production, the ...
