Kinetic mixing, dark photons and extra dimensions. Part III. Brane localized dark matter

open access: yesJournal 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 ...

Probing the anomalous γγγZ coupling at the LHC with proton tagging

open access: yesJournal 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.

Explaining Atomki anomaly and muon g − 2 in U(1) X extended flavour violating two Higgs doublet model

open access: yesJournal 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.

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

open access: yesJournal 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.

Interpreting the 3 TeV WH resonance as a W′ boson

open access: yesJournal 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,

Bubble needs strings

open access: yesJournal of High Energy Physics, 2021
In this paper, we want to emphasize the pivotal role played by strings in the model realizing de Sitter using an expanding bubble, proposed and subsequently developed in [1–3].

Incorporation of Organic Counter‐Cations Into Poly(Heptazine Imide) Networks for Promoting Proton‐Coupled Electron Transfer During Photocatalytic H2O2 Evolution

open access: yesAngewandte Chemie, EarlyView.
Incorporation of N‐based onium ions into the ionic framework of poly(heptazine imide) was obtained via protonation‐deprotonation of PHI frameworks arising from a parent Na‐containing analogue. Particularly, methylammonium moieties, through their small molecular size, hydrogen bonding capabilities and rotational mobility, appear to stabilize ...

Gapped continuum Kaluza-Klein spectrum

open access: yesJournal of High Energy Physics, 2019
We consider a warped five-dimensional model with an ultraviolet (UV) brane and, on top of the Standard Model isolated modes, continua of KK modes with different mass gaps for all particles: gauge bosons, fermions, graviton, radion and Higgs boson.

Kinetic mixing, dark photons and an extra dimension. Part I

open access: yesJournal 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 ...

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

open access: yesJournal 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.
