Dark matter and collider signals in an MSSM extension with vector-like multiplets (2018)
Journal Article
Araz, J. Y., Banerjee, S., Frank, M., Fuks, B., & Goudelis, A. (2018). Dark matter and collider signals in an MSSM extension with vector-like multiplets. Physical Review D, 98(11), Article 115009. https://doi.org/10.1103/physrevd.98.115009

Motivated by grand unification considerations, we analyse a simple extension of the minimal supersymmetric standard model with additional pairs of vector-like chiral supermultiplets. We focus on the so-called LND setup, which enlarges the particle co... Read More about Dark matter and collider signals in an MSSM extension with vector-like multiplets.

Novel signature for long-lived particles at the LHC (2018)
Journal Article
Banerjee, S., Bélanger, G., Bhattacherjee, B., Boudjema, F., Godbole, R. M., & Mukherjee, S. (2018). Novel signature for long-lived particles at the LHC. Physical Review D, 98(11), Article 115026. https://doi.org/10.1103/physrevd.98.115026

In contrast to the decay products ensuing from a fast moving particle which are collimated along the original direction of the parent, those from a slow moving particle are distributed over a wide region. In the context of searches for heavy long-liv... Read More about Novel signature for long-lived particles at the LHC.

Probing electroweak precision physics via boosted Higgs-strahlung at the LHC (2018)
Journal Article
Banerjee, S., Englert, C., Gupta, R. S., & Spannowsky, M. (2018). Probing electroweak precision physics via boosted Higgs-strahlung at the LHC. Physical Review D, 98(9), Article 095012. https://doi.org/10.1103/physrevd.98.095012

We study the process pp → Zðlþl−Þhðbb¯Þ in the standard model effective field theory (SMEFT) at high energies using subjet techniques to reconstruct the Higgs boson. We show that at high energies this process probes four directions in the dimension-6... Read More about Probing electroweak precision physics via boosted Higgs-strahlung at the LHC.

Long-lived stau, sneutrino dark matter and right-slepton spectrum (2018)
Journal Article
Banerjee, S., Bélanger, G., Ghosh, A., & Mukhopadhyaya, B. (2018). Long-lived stau, sneutrino dark matter and right-slepton spectrum. Journal of High Energy Physics, 2018(9), Article 143. https://doi.org/10.1007/jhep09%282018%29143

The minimal supersymmetric (SUSY) standard model (MSSM) augmented by right chiral sneutrinos may lead to one such sneutrino serving as the lightest supersymmetric particle and a non-thermal dark matter candidate, especially if neutrinos have Dirac ma...

Revisiting the non-resonant Higgs pair production at the HL-LHC (2018)
Journal Article
Adhikary, A., Banerjee, S., Barman, R. K., Bhattacherjee, B., & Niyogi, S. (2018). Revisiting the non-resonant Higgs pair production at the HL-LHC. Journal of High Energy Physics, 2018(7), Article 116. https://doi.org/10.1007/jhep07%282018%29116

We study the prospects of observing the non-resonant di-Higgs pair production in the Standard Model (SM) at the high luminosity run of the 14 TeV LHC (HL-LHC), upon combining multiple final states chosen on the basis of their yield and cleanliness. I... Read More about Revisiting the non-resonant Higgs pair production at the HL-LHC.

hh+Jet production at 100 TeV (2018)
Journal Article
Banerjee, S., Englert, C., Mangano, M. L., Selvaggi, M., & Spannowsky, M. (2018). hh+Jet production at 100 TeV. The European Physical Journal C, 78(4), Article 322. https://doi.org/10.1140/epjc/s10052-018-5788-y

Higgs pair production is a crucial phenomenological process in deciphering the nature of the TeV scale and the mechanism underlying electroweak symmetry breaking. At the Large Hadron Collider, this process is statistically limited. Pushing the energy... Read More about hh+Jet production at 100 TeV.
