Kinetic mixing, dark photons and an extra dimension. Part I
Journal of High Energy Physics, 2018 Extra dimensions (ED) can provide a useful tool for model-building. In this paper we introduce a single, flat ED extension of the kinetic-mixing/dark photon (DP) portal for dark matter (DM) interactions with the Standard Model (SM) assuming a ...

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 ...

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 ...

LHC constraints on hidden gravitons
Journal of High Energy Physics, 2022 We analyze LHC data in order to constrain the parameter space of new spin-2 particles universally coupled to the energy-momentum tensor. These new hypothetical particles are the so-called hidden gravitons, whose phenomenology at low energies is ...

Analytical Green’s functions for continuum spectra
Journal of High Energy Physics, 2021 Green’s functions with continuum spectra are a way of avoiding the strong bounds on new physics from the absence of new narrow resonances in experimental data.

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, 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 ...

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-

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 ...
