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 ...

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.

Kinetic mixing, dark photons and extra dimensions. Part III. Brane localized dark matter
Journal of High Energy Physics, 2021 Extra dimensions have proven to be a very useful tool in constructing new physics models. In earlier work, we began investigating toy models for the 5-D analog of the kinetic mixing/vector portal scenario where the interactions of dark matter, taken to ...

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 ...

Journal of High Energy Physics, 2020 In this paper, we explore the possibility that a light dilaton can be the first sign of new physics at the LHC. The dilaton could emerge in approximate scale invariant UV completions of the SM as the Goldstone boson associated with the spontaneous ...

Probing the anomalous γγγZ coupling at the LHC with proton tagging
Journal of High Energy Physics, 2017 The sensitivities to the anomalous quartic gauge boson coupling γγγZ are estimated via γZ production with intact protons in the forward region at the LHC.

Gravity-mediated dark matter annihilation in the Randall-Sundrum model
Journal of High Energy Physics, 2017 Observational evidence for dark matter stems from its gravitational interactions, and as of yet there has been no evidence for dark matter interacting via other means. We examine models where dark matter interactions are purely gravitational in a Randall-

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.
