Nonminimal couplings and preheating effects in -Higgs inflation after ACT and SPT
Haneesh Gonuguntla, Tanmoy Modak, Arnab Samanta
We study the effects of dimension-four and dimension-six nonminimal Higgs couplings to the Ricci scalar in the -Higgs inflation model in light of the recent ACT and SPT ob…
Echoes of modification and Goldstone preheating in the CMB-BAO landscape
Tanmoy Modak
The and the single-field-like regime of -Higgs inflation are disfavored by the observed high spectral index from the combined cosmic microwave background (CMB) and…
The -Higgs inflation: contribution and preheating after ACT and SPT data
Tanmoy Modak
The -Higgs inflation is one of the simplest yet best-fit models consistent with Planck data. The higher spectral index recently reported by the combined cosmic microwave…
A Global View of the EDM Landscape
Skyler Degenkolb, Nina Elmer, Tanmoy Modak +2
Permanent electric dipole moments (EDMs) are sensitive probes of the symmetry structure of elementary particles, which in turn is closely tied to the baryon asymmetry in the univer…
Semi-visible jets, energy-based models, and self-supervision
Luigi Favaro, Michael Krämer, Tanmoy Modak +2
We present DarkCLR, a novel framework for detecting semi-visible jets at the LHC. DarkCLR uses a self-supervised contrastive-learning approach to create observables that are approx…
