Searching for dark jets with displaced vertices using weakly supervised machine learning
Debjyoti Bardhan, Yevgeny Kats, Noam Wunch
If "dark quarks" from a confining hidden sector are produced at the LHC, they will shower and hadronize to dark sector hadrons, which may decay back to Standard Model particles wit…
Bounds on boosted dark matter from direct detection: The role of energy-dependent cross sections
Debjyoti Bardhan, Supritha Bhowmick, Diptimoy Ghosh +2
The recoil threshold of Direct Detection experiments limits the mass range of Dark Matter (DM) particles that can be detected, with most DD experiments being blind to sub-MeV DM pa…
from RPV-SUSY sneutrinos
Debjyoti Bardhan, Diptimoy Ghosh, Divya Sachdeva
We analyze the lepton flavor universality violation (LFV) in process in an R-parity violating supersymmetric (RPV-SUSY) scenario. The most recent update on $\…
Towards constraining triple gluon operators through tops
Debjyoti Bardhan, Diptimoy Ghosh, Prasham Jain +1
Effective field theory techniques provide us important tools to probe for physics beyond the Standard Model in a relatively model-independent way. In this work, we revisit the CP-e…
B-meson charged current anomalies: the post-Moriond status
Debjyoti Bardhan, Diptimoy Ghosh
In this note, we discuss the impact of the recent Belle result on the various theoretical explanations of the and anomalies. The pure tensor explanation, which was…
Anatomy of anomalies
Aleksandr Azatov, Debjyoti Bardhan, Diptimoy Ghosh +2
In recent times, one of the strongest hints of Physics Beyond the Standard Model (BSM) has been the anomaly in the ratios and measured in the charged current dec…
FCNC Decays of the Top Quark
Debjyoti Bardhan
If new physics (e.g. SUSY) does not show up as direct evidence at the LHC, it could still be observable in FCNC processes involving the -quark. We take a close look at the proce…
A Closer Look at and
Debjyoti Bardhan
The measurement of (), the ratio of the branching fraction of to that of $\overline{B} \to D l \barν_l (…
Role of Tensor operators in and
Debjyoti Bardhan, Pritibhajan Byakti, Diptimoy Ghosh
The recent LHCb measurement of in two bins, when combined with the earlier measurement of , strongly suggests lepton flavour non-universal new physics in semi-…
Search for bottom squarks in the baryon-number violating MSSM
Debjyoti Bardhan, Amit Chakraborty, Debajyoti Choudhury +2
We consider a scenario of Minimal Supersymmetric Standard Model (MSSM) with -parity violation, where the lightest supersymmetric particle (LSP) is the lighter sbottom $(\tilde b…
A closer look at the and anomalies
Debjyoti Bardhan, Pritibhajan Byakti, Diptimoy Ghosh
The measurement of (), the ratio of the branching fraction of to that of $\overline{B} \to D l \barν_l (…
The 750 GeV diphoton resonance as an sgoldstino: a reappraisal
Debjyoti Bardhan, Pritibhajan Byakti, Diptimoy Ghosh +1
Among the various explanations of the possible 750 GeV diphoton resonance, the possibility of it being an sgoldstino is an attractive one, as it is related to the spontaneous break…
Radion Candidate for the LHC Diphoton Resonance
Debjyoti Bardhan, Disha Bhatia, Amit Chakraborty +3
The recent observation of a modest excess in diphoton final states at the LHC, by both the ATLAS and CMS Collaborations, has sparked off the expected race among theorists to find t…
A Detailed Analysis of Flavour-changing Decays of Top Quarks as a Probe of New Physics at the LHC
Debjyoti Bardhan, Gautam Bhattacharyya, Diptimoy Ghosh +2
If the LHC should fail to observe direct signals for new physics, it may become necessary to look for new physics effects in rare events such as flavour-changing decays of the top…
