Hydrogen 21 cm Constraints on the Photon's Spin Scale
Aidan Reilly, Alessandro Russo, Philip Schuster +1
We explore the fundamental but untested possibility that the photon is a continuous spin particle (CSP) with a small but non-zero spin Casimir . When , the familiar p…

Probing "Continuous Spin" QED with Rare Atomic Transitions
Aidan Reilly, Philip Schuster, Natalia Toro
An intriguing and elementary possibility is that familiar massless particles like the photon could be "continuous spin" particles (CSP) with a small but non-zero spin Casimir .…
