Efficient description of experimental effects in amplitude analyses
Abhijit Mathad, Daniel O'Hanlon, Anton Poluektov +1
Amplitude analysis is a powerful technique to study hadron decays. A significant complication in these analyses is the treatment of instrumental effects, such as background and sel…
Spectroscopic Constraints on (pseudo-)Scalar Particles from Compact Astrophysical Objects
Doron Chelouche, Raul Rabadan, Sergey Pavlov +1
We propose a new method to search for light (pseudo-)scalar particles in the spectra of compact astrophysical objects such as magnetars, pulsars, and quasars. On accounts of compac…
Spectral Signatures of Photon-Particle Oscillations from Celestial Objects
Doron Chelouche, Raul Rabadan, Sergey Pavlov +1
We give detailed predictions for the spectral signatures arising from photon-particle oscillations in astrophysical objects. The calculations include quantum electrodynamic effects…
Photon Regeneration from Pseudoscalars at X-ray Laser Facilities
Raul Rabadan, Andreas Ringwald, Kris Sigurdson
Recently, the PVLAS collaboration has reported an anomalously large rotation of the polarization of light in the presence of a magnetic field. As a possible explanation they consid…
Non-perturbative orientifold transitions at the conifold
Kentaro Hori, Kazuo Hosomichi, David C. Page +2
After orientifold projection, the conifold singularity in hypermultiplet moduli space of Calabi-Yau compactifications cannot be avoided by geometric deformations. We study the non-…
Stability in Asymptotically AdS Spaces
M. Kleban, M. Porrati, R. Rabadan
We discuss two types of instabilities which may arise in string theory compactified to asymptotically AdS spaces: perturbative, due to discrete modes in the spectrum of the Laplaci…
