Proof of dispersion relations for the amplitude in theories with a compactified space dimension

Journal of High Energy Physics, 2020
The analyticity properties of the scattering amplitude in the nonforward direction are investigated for a field theory in the manifold R 3,1 ⨂ S 1.

Astrophysical constraints on large extra dimensions [PDF]

Physics Letters B, 1999
In the Kaluza-Klein (KK) scenario with n large extra dimensions where gravity propagates in the 4+n dimensional bulk of spacetime while gauge and matter fields are confined to a four dimensional subspace, the light graviton KK modes can be produced in the Sun, red giants and supernovae. We study the energy-loss rates through photon-photon annihilation,

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.

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.

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-

Artificial proto-modelling: building precursors of a next standard model from simplified model results

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 ...

MIRROR WORLD VERSUS LARGE EXTRA DIMENSIONS [PDF]

Modern Physics Letters A, 1999
Recently proposed low scale quantum gravity scenario is expected to have a significant impact on the mirror world hypothesis. Some aspects of this influence is investigated here, assuming that the fundamental gravity scale is near a TeV. It is shown that future colliders will be capable of producing the mirror matter, but an experimental signature ...
