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…
Bound on largest from sub-Planckian excursions of inflaton
Arindam Chatterjee, Anupam Mazumdar
In this paper we will discuss the range of large tensor to scalar ratio, , obtainable from a sub-Planckian excursion of a {\it single}, {\it slow roll} driven inflaton field. In…
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…
