Spin Correlation and Quantum Entanglement of Fermion Pairs in Transversely Polarized Collisions
Yi-Jing Fang, Amit Bhoonah, Kun Cheng +3
We systematically study the spin correlations and quantum entanglement in transversely polarized electron-positron collisions. We find that the -channel QED process $e^-e^+\to f…
The NANOGrav 15 yr Data Set: Piecewise Power-Law Reconstruction of the Gravitational-Wave Background
Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +108
The NANOGrav 15-year (NG15) data set provides evidence for a gravitational-wave background (GWB) signal at nanohertz frequencies, which is expected to originate either from a cosmi…
Galactic magnetic fields seeded by ultralight dark photons
Joshua Berger, Amit Bhoonah, Joseph Bramante +3
In this work, we show that ultralight dark photons, which couple to the Standard Model photon through kinetic mixing, can potentially source galactic scale magnetic fields. Althoug…
A Baryon and Lepton Number Violation Model Testable at the LHC
Amit Bhoonah, Francis Burk, Da Liu +2
Proton decay experiments typically constrain baryon number violation to the scale of grand unified theories. From a phenomenological point of view, this makes direct probing of the…
Sub-MHz Radio Background from Ultralight Dark Photon Dark Matter
Javier F. Acevedo, Amit Bhoonah, Kun Cheng
Dark photons are a well-motivated candidate for dark matter, but their detection becomes challenging for ultralight masses with both experimental and astrophysical probes. In this…
Right-Handed Neutrino Masses from the Electroweak Scale
Brian Batell, Amit Bhoonah, Wenjie Huang
Heavy right-handed neutrinos are highly motivated due to their connection with the origin of neutrino masses via the seesaw mechanism. If the right-handed neutrino Majorana mass is…
Axion Electrodyanmics in the Presence of Current Sources
Joshua Berger, Amit Bhoonah
Axions are among the most sought-after candidates for dark matter. In the ultralight regime, they could help alleviate puzzles in small scale cosmology. Searches for a halo of axio…
Probing Exotic Phases Via Stochastic Gravitational Wave Spectra
Joshua Berger, Amit Bhoonah, Biswajit Padhi
Stochastic backgrounds of gravitational waves (GWs) from the pre-BBN era offer a unique opportunity to probe the universe beyond what has already been achieved with the Cosmic Micr…
Detecting axion dark matter with Rydberg atoms via induced electric dipole transitions
Georg Engelhardt, Amit Bhoonah, W. Vincent Liu
Long-standing efforts to detect axions are driven by two compelling prospects, naturally accounting for the absence of charge-conjugation and parity symmetry breaking in quantum ch…
Diffuse X-Ray and Gamma-Ray Limits on Boson Stars that Interact with Nuclei
Javier F. Acevedo, Amit Bhoonah, Joseph Bramante
Light bosonic dark matter can form gravitationally bound states known as boson stars. In this work, we explore a new signature of these objects interacting with the interstellar me…
Laboratory constraints on ultralight axion-like particles from precision atomic spectroscopy
Joshua Berger, Amit Bhoonah
Ultralight bosonic dark matter has come under increasing scrutiny as a dark matter candidate that has the potential to resolve puzzles in astronomical observation. We demonstrate t…
Etching Plastic Searches for Dark Matter
Amit Bhoonah, Joseph Bramante, Brian Courtman +1
Large panels of etched plastic, situated aboard the Skylab Space Station and inside the Ohya quarry near Tokyo, have been used to set limits on fluxes of cosmogenic particles. Thes…
Detecting Composite Dark Matter with Long Range and Contact Interactions in Gas Clouds
Amit Bhoonah, Joseph Bramante, Sarah Schon +1
Cold interstellar gas clouds provide an exciting new method to discover dark matter. Their immense size makes them uniquely sensitive to interactions from the heaviest, most rarefi…
Gravitational Waves From Dark Sectors, Oscillating Inflatons, and Mass Boosted Dark Matter
