Multi-Lepton Probes of the Drell-Yan Production of Triplet Higgses

Siddharth P. Maharathy, Srimoy Bhattacharya, Andreas Crivellin +3

Excesses in di-photon, $Z γ$ , and $W W$ spectra indicate the existence of a new Higgs boson with mass $152 \pm 1$ GeV. However, no excess is observed in the $Z Z$ channel. This patter…

Emerging Narrow Resonance at 152 GeV

Srimoy Bhattacharya, Mukesh Kumar, Rachid Mazini +1

The discovery of the Higgs boson at the LHC completed the Standard Model (SM), yet the possibility of additional scalars remains open, provided their contributions to electroweak s…

Discovery Prospects for the 150 GeV charged scalar at Future $e^{+} e^{-}$ Colliders

Siddharth P. Maharathy, Phodiso Maroeshe, Paballo Ndhlovu +5

The Real Higgs Triplet model, known as the $Δ$ SM, is a minimal extension of the Standard Model (SM) obtained by adding a hypercharge 0 triplet ( $Δ$ ). This simple model is motivated…

Emerging Excess Consistent with a Narrow Resonance at 152 GeV in High-Energy Proton-Proton Collisions

Srimoy Bhattacharya, Benjamin Lieberman, Mukesh Kumar +4

The Higgs boson discovery at the Large Hadron Collider (LHC) at CERN confirmed the existence of the last missing particle of the Standard Model (SM). The existence of new fundament…

Axion Icebergs: Clockwork ALPs at hadron colliders

Srimoy Bhattacharya, Debajyoti Choudhury, Suvam Maharana +1

Scenarios with multiple pseudoscalars are interesting as they usually tend to provide a framework to naturally realize a light axion with a large decay constant which has rich appl…

COVID-19 South African Vaccine Hesitancy Models Show Boost in Performance Upon Fine-Tuning on M-pox Tweets

Nicholas Perikli, Srimoy Bhattacharya, Blessing Ogbuokiri +8

Very large numbers of M-pox cases have, since the start of May 2022, been reported in non-endemic countries leading many to fear that the M-pox Outbreak would rapidly transition in…

Detecting the Presence of COVID-19 Vaccination Hesitancy from South African Twitter Data Using Machine Learning

Nicholas Perikli, Srimoy Bhattacharya, Blessing Ogbuokiri +8

Very few social media studies have been done on South African user-generated content during the COVID-19 pandemic and even fewer using hand-labelling over automated methods. Vaccin…

Growing Excesses of New Scalars at the Electroweak Scale

Srimoy Bhattacharya, Guglielmo Coloretti, Andreas Crivellin +4

We combine searches for scalar resonances at the electroweak scale performed by the Large Hadron Collider experiments ATLAS and CMS where persisted excesses have been observed in r…

Searching for Low-Mass Resonances Decaying into $W$ Bosons

Guglielmo Coloretti, Andreas Crivellin, Srimoy Bhattacharya +1

In this article, we recast and combine the CMS and ATLAS analyses of the Standard Model Higgs boson decaying to a pair of $W$ bosons in order to search for low-mass resonances in t…

Accumulating Evidence for the Associated Production of a New Higgs Boson at the Large Hadron Collider

Andreas Crivellin, Yaquan Fang, Oliver Fischer +7

In the last decades, the Standard Model (SM) of particle physics has been extensively tested and confirmed, with the announced discovery of the Higgs boson in 2012 being the last m…

'Deep' Dive into $b \to c$ Anomalies: Standardized and Future-proof Model Selection Using Self-normalizing Neural Networks

Srimoy Bhattacharya, Soumitra Nandi, Sunando Kumar Patra +1

Noting the erroneous proclivity of information-theoretic approaches, like the Akaike information criterion (AIC), to select simpler models while performing model selection with a s…

A detailed study of the $Λ_{b} \to Λ ℓ^{+} ℓ^{-}$ decays in the Standard Model

Srimoy Bhattacharya, Soumitra Nandi, Sunando Kumar Patra +1

Based on the standard model (SM) of particle physics, we study the decays $Λ_{b} \to Λ ℓ^{+} ℓ^{-}$ in light of the available inputs from lattice and the data from LHCb. We fit the…

An in-depth analysis of $b \to c (s)$ semileptonic observables with possible $μ - τ$ mixing

Srimoy Bhattacharya, Aritra Biswas, Zaineb Calcuttawala +1

In a couple of recent publications ( arXiv:1706.08437 and arXiv:1712.01593 ), the authors attempted to achieve simultaneous explanation of the persistent flavor anomalies in $b\to…

Looking for possible new physics in $B \to D^{(*)} τ ν_{τ}$ in light of recent data

Srimoy Bhattacharya, Soumitra Nandi, Sunando K. Patra

We study the decays $B \to D^{(*)} τ ν_{τ}$ in light of the available data from BABAR, Belle and LHCb. We divide our analysis into two parts: in one part we fit the form-factors in t…
