UV Shadows in EFTs: Accidental Symmetries, Robustness and No‐Scale Supergravity

open access: yesFortschritte der Physik, Volume 68, Issue 10, October 2020., 2020
Abstract We argue that accidental approximate scaling symmetries are robust predictions of weakly coupled string vacua, and show that their interplay with supersymmetry and other (generalised) internal symmetries underlies the ubiquitous appearance of no‐scale supergravities in low‐energy 4D EFTs.

Supergravity Model of Inflation and Explaining IceCube HESE Data via PeV Dark Matter Decay

open access: yesAdvances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020
We construct a unified model of inflation and PeV dark matter with an appropriate choice of no‐scale Kähler potential, superpotential, and gauge kinetic function in terms of MSSM fields and hidden sector Polonyi field. The model is consistent with the CMB observations and can explain the PeV neutrino flux observed at IceCube HESE.

Testing Yukawa unification at LHC Run-3 and HL-LHC

open access: yesJournal of High Energy Physics, 2020
We explore t-b-τ Yukawa unification (YU) in a supersymmetric SU(4) c × SU(2) L × SU(2) R model without imposing a discrete left-right (L-R) symmetry.

How heavy can neutralino dark matter be?

open access: yesJournal of High Energy Physics, 2019
What is the upper limit of the mass of the neutralino dark matter whose thermal relic is consistent with the observation? If the neutralino dark matter and colored sparticles are extremely degenerated in mass, with a mass difference less than the QCD ...

Analysis of the neutralino system in three–body leptonic decays of neutralinos [PDF]

open access: yesThe European Physical Journal C, 2006
Neutralinos $\tilde ^0$ in supersymmetric theories, the spin--1/2 Majorana--type superpartners of the U(1) and SU(2) neutral electroweak gauge bosons and SU(2) neutral Higgs bosons, are expected to be among light supersymmetric particles so that they can be produced copiouslyvia direct pair production and/or from cascade decays of other sparticles ...

Searches for pair production of charginos and top squarks in final states with two oppositely charged leptons in proton-proton collisions at s = 13 $$ \sqrt{s}=13 $$ TeV

open access: yesJournal of High Energy Physics, 2018
A search for pair production of supersymmetric particles in events with two oppositely charged leptons (electrons or muons) and missing transverse momentum is reported. The data sample corresponds to an integrated luminosity of 35.9 fb−1 of proton-proton
