Neutrino superradiance constraint on asteroid-mass PBH Dark Matter and beyond
Yi-Xuan Lin, Priyanka Sarmah, Martin Spinrath
Primordial Black Holes (PBHs) are an attractive candidate for Dark Matter (DM) and there has been extensive experimental efforts to look for them. The asteroid-mass window, $M_{\te…
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…
Exploring interference effects between two ALP effective operators at the LHC
Kingman Cheung, Chih-Ting Lu, C. J. Ouseph +1
We observe that most studies of axion-like particle (ALP) production channels at the Large Hadron Collider (LHC) focus on a single type of ALP operator for each process in the effe…
Effects of Superradiance in Active Galactic Nuclei
Priyanka Sarmah, Himanshu Verma, Kingman Cheung +1
A supermassive black hole (SMBH) at the core of an active galactic nucleus (AGN) provides room for the elusive ultra-light scalar particles (ULSP) to be produced through a phenomen…
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…
Polarized cross sections in Higgsstrahlung for the determination of anomalous couplings
Kumar Rao, Saurabh D. Rindani, Priyanka Sarmah +1
The production of a Higgs boson in association with a at an electron-positron collider is one of the cleanest methods for the measurement of the couplings of the Higgs boson. I…

The production of a Higgs boson in association with a at an electron-positron collider is one of the cleanest methods for the measurement of the couplings of the Higgs boson. I…
Use of polarization in to measure the triple-Higgs coupling
Kumar Rao, Saurabh D. Rindani, Priyanka Sarmah +1
It is shown that a certain angular asymmetry of charged leptons produced in the decay of in the process , related to a tensor polarization component of the ,…
A strong broadband 21 cm cosmological signal from dark matter spin-flip interactions
Mansi Dhuria, Viraj Karambelkar, Vikram Rentala +1
In the standard cosmology, it is believed that there are two relatively weak and distinct band-limited absorption features, with the first absorption minima near 20 MHz ()…
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…
