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

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 ...

Constraining compressed versions of MUED and MSSM using soft tracks at the LHC

Journal of High Energy Physics, 2017
A compressed spectrum is an anticipated hideout for many beyond standard model scenarios. Such a spectrum naturally arises in the minimal universal extra dimension framework and also in supersymmetric scenarios.

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.

Interpreting the 3 TeV WH resonance as a W′ boson

Journal of High Energy Physics, 2017
Motivated by a local 3.2 − 3.4 sigma resonance in WH and ZH in the ATLAS Run 2 data, we attempt to interpret the excess in terms of a W′ boson in a SU(2)1 × SU(2)2×U(1)X model. We stretch the deviation from the alignment limit of the Equivalence Theorem,

Exact greybody factors for the brane scalar field of five-dimensional rotating black holes

Journal of High Energy Physics, 2019
We study scalar perturbations of the five-dimensional rotating black holes and find an exact solution giving exact description of the Hawking radiation.

R D * $$ {R}_{D^{\left(*\right)}} $$ in custodial warped space

Journal of High Energy Physics, 2018
Flavor physics experiments allow to probe the accuracy of the Standard Model (SM) description at low energies, and are sensitive to new heavy gauge bosons that couple to quarks and leptons in a relevant way.

Electroweak Kaluza-Klein dark matter

Journal of High Energy Physics, 2017
In models with universal extra dimensions (UED), the lightest Kaluza-Klein excitation of neutral electroweak gauge bosons is a stable, weakly interacting massive particle and thus is a candidate for dark matter thanks to Kaluza-Klein parity.

g μ − 2 from Vector-like leptons in warped space

Journal of High Energy Physics, 2017
The experimental value of the anomalous magnetic moment of the muon, as well as the LHCb anomalies, point towards new physics coupled non-universally to muons and electrons.

Dark bubbles: decorating the wall

Journal of High Energy Physics, 2020
Motivated by the difficulty of constructing de Sitter vacua in string theory, a new approach was proposed in arXiv:1807.01570 and arXiv:1907.04268 , where four dimensional de Sitter space was realized as the effective cosmology, with matter and radiation,
