Confronting electroweak MSSM through one-loop renormalized neutralino-Higgs interactions for dark matter direct detection and muon
Subhadip Bisal, Arindam Chatterjee, Debottam Das +1
We compute the next-to-leading order (NLO) corrections to the vertices where a pair of the lightest neutralino couples to CP-even (light or heavy) Higgs scalars. In particular, the…
Radiative Corrections to Aid the Direct Detection of the Higgsino-like Neutralino Dark Matter: Spin-Independent Interactions
Subhadip Bisal, Arindam Chatterjee, Debottam Das +1
The lightest neutralino () is a good Dark Matter (DM) candidate in the R-parity conserving Minimal Supersymmetric Standard Model (MSSM). In this work, we consider the…
Prospects of a Strong first-order Electroweak Phase Transition in the -NMSSM
Arindam Chatterjee, AseshK Datta, Subhojit Roy
We have studied the viability and possible patterns of a strong first-order electroweak phase transition (SFOEWPT) within the -symmetric Next-to-Minimal Supersymmetric Standar…
Electroweak Phase Transition in the -invariant NMSSM: Implications of LHC and Dark matter searches and prospects of detecting the gravitational waves
Arindam Chatterjee, AseshKrishna Datta, Subhojit Roy
We study in detail the viability and the patterns of a strong first-order electroweak phase transition as a prerequisite to electroweak baryogenesis in the framework of -invar…
Shedding Light on Dark Matter and Neutrino Interactions from Cosmology
Arnab Paul, Arindam Chatterjee, Anish Ghoshal +1
In CDM cosmology, Dark Matter (DM) and neutrinos are assumed to be non-interacting. However, it is possible to have scenarios, where DM-neutrino interaction may be present, l…
Revisiting singlino dark matter of the natural -symmetric NMSSM in the light of LHC
Waleed Abdallah, Arindam Chatterjee, AseshKrishna Datta
Inspired by the fact that relatively small values of the effective higgsino mass parameter of the -symmetric Next-to-Minimal Supersymmetric Standard Model (NMSSM) could render…
Scope of strongly self-interacting thermal WIMPs in a minimal extension and its future prospects
Rahool Kumar Barman, Biplob Bhattacherjee, Arindam Chatterjee +2
In this work we have considered a minimal extension of Standard Model by a local gauge group in order to accommodate a stable (fermionic) Dark Matter (DM) candidate. We have…
Multileptonic signals of co-annihilating left-right supersymmetric dark matter
Arindam Chatterjee, Mariana Frank, Benjamin Fuks +4
We perform a comprehensive dark matter analysis of left-right supersymmetric scenarios that includes constraints from dark matter direct and indirect detection experiments and that…
Non-thermal production of Dark Matter after Inflation
Nicolás Bernal, Arindam Chatterjee, Arnab Paul
The existence of Dark Matter (DM) has been well established from various cosmological and astrophysical evidences. However, the particle properties of DM are largely undetermined a…
Natural SUSY at LHC with Right-Sneutrino LSP
Arindam Chatterjee, Juhi Dutta, Santosh Kumar Rai
We study an extension of the minimal supersymmetric standard model (MSSM) with additional right-handed singlet neutrino superfields. While such an extension incorporates a mechanis…
Sbottoms of Natural NMSSM at the LHC
Jyotiranjan Beuria, Arindam Chatterjee, AseshKrishna Datta
Search for the bottom squarks (sbottoms) at the Large Hadron Collider (LHC) has recently assumed a heightened focus in the hunt for Supersymmetry (SUSY). The popular framework of t…
Two Light Stops in the NMSSM and the LHC
Jyotiranjan Beuria, Arindam Chatterjee, AseshKrishna Datta +1
We study the viability of having two relatively light top squarks (`stops') in the framework of the Next-to-Minimal Supersymmetric Standard Model (NMSSM). Such light stops render t…
Same-sign trileptons as a signal of sneutrino lightest supersymmetric partlcle
Nabarun Chakrabarty, Arindam Chatterjee, Biswarup Mukhopadhyaya
Contrary to common expectation, a left-sneutrinos can occasionally be the lightest supersymmet- ric particle. This has important implications in both collider and dark matter studi…
Gluino mass limits with sbottom NLSP in coannihilation scenarios
Arindam Chatterjee, Arghya Choudhury, Amitava Datta +1
In view of the recent interest in the pMSSM with light third generation squarks, we consider a hitherto neglected scenario where the lighter bottom squark () is th…
Resurrecting Sneutrino () Dark Matter in light of Neutrino Mass and LUX
Arindam Chatterjee, Narendra Sahu
In the minimal supersymmetric standard model (MSSM) the lightest superpartner of the left-handed neutrinos is ruled out of being a candidate of dark matter because of its large ela…
Right Sneutrino Dark Matter and a Monochromatic Photon Line
Arindam Chatterjee, Debottam Das, Biswarup Mukhopadhyaya +1
The inclusion of right-chiral sneutrino superfields is a rather straightforward addition to a supersymmetric scenario. A neutral scalar with a substantial right sneutrino component…
On the On-Shell Renormalization of the Chargino and Neutralino Masses in the MSSM
Arindam Chatterjee, Manuel Drees, Suchita Kulkarni +1
We discuss the choice of input parameters for the renormalization of the chargino and neutralino sector in the minimal supersymmetric standard model (MSSM) in the on-shell scheme.…
Tuned MSSM Higgses as an inflaton
Arindam Chatterjee, Anupam Mazumdar
We consider the possibility that the vacuum energy density of the MSSM (Minimal Supersymmetric Standard Model) flat direction condensate involving the Higgses H_1 and H_2 is respon…
