Microlensing Black Hole Shadows-II: Constraining Primordial Black Hole Dark Matter using the photon rings of M87 and Sgr A*
Himanshu Verma, Priyanka Sarmah, Joseph Silk +1
The resolution of photon rings of Sgr~A and M87 is the next milestone of upcoming EHT-like interferometries. We extend the formalism developed in our previous work~\cite{Verma:…
Probing memory-burdened Primordial Black Holes with global 21 cm signal
Priyanka Sarmah, Kingman Cheung
We investigate the imprints of memory-burdened primordial black holes (PBH) on the global 21 cm signal during the cosmic dawn. Recent studies reopened the possibility of a mass win…
polarization at an collider and properties of decay-lepton angular asymmetries
Kumar Rao, Saurabh D. Rindani, Priyanka Sarmah +1
production at an collider, associated with production of other particles, can be an accurate source of information of details of electroweak interactions, including po…
Study of anomalous gauge-Higgs couplings using boson polarization at LHC
Kumar Rao, Saurabh D. Rindani, Priyanka Sarmah
We estimate model-independent bounds that could be obtained on the anomalous vertex using polarization parameters of the boson produced in the Higgstrahlung process at th…
Probing anomalous gauge-Higgs couplings using boson polarization at colliders
Kumar Rao, Saurabh D. Rindani, Priyanka Sarmah
We study possible new physics interactions in the vertex contributing to the Higgsstrahlung process at proposed future colliders using the polarizat…
