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-

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.

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.

Large Extra Dimensions [PDF]

, 2020
The possibility of extra dimensions has been considered for a long time. In the 1920's, Kaluza and Klein sought to unify electromagnetism with gravity by adding an extra dimension that was curled up on the order of the Planck length (10 -35 m.) Then,

A short travel for neutrinos in Large Extra Dimensions

Journal of High Energy Physics, 2018
Neutrino oscillations successfully explain the flavor transitions observed in neutrinos produced in natural sources like the center of the sun and the earth atmosphere, and also from man-made sources like reactors and accelerators. These oscillations are

Activated sphalerons and large extra dimensions [PDF]

Physical Review D, 2002
We present a new scenario for the baryon number violation that may take place in models with large extra dimensions. Our idea is interesting because leptogenesis with a low reheating temperature requires an alternative source of the B+L violation to convert the produced leptons into baryons.

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.

Smooth braneworld in 6-dimensional asymptotically AdS spacetime

Journal of High Energy Physics, 2021
In this paper, we investigate a six-dimensional smooth thick braneworld model which contains a compact extra dimension and an infinite large one. The braneworld is generated by a real scalar field with a ϕ 6 potential and the bulk is an asymptotically ...

Cosmological perturbations from five-dimensional inflation

Journal of High Energy Physics
It was recently proposed that five-dimensional inflation can relate the causal size of the observable universe to the present weakness of gravitational interactions by blowing up an extra compact dimension from the microscopic fundamental length of ...
