Workshop
19 Apr, 2021 - 21 May, 2021
The purpose of the workshop is to gather theorists working on apparently different areas which are nevertheless connected to the recent discovery of gravitational waves. More specifically its aims are to: (i) deepen links and foster new collaborations between the quantum gravitational scattering amplitude and the GR community, leading to the calculation of new, high-order, terms in the post-Newtonian and post-Minkowskian perturbative approaches to the physics of binary systems; (ii) identify new synergies between the GR analytical and numerical communities which have already proved to be so crucial in constructing the waveform templates necessary for the analysis of LIGO/Virgo data; (iii) use recent progress on gravitational scattering and radiation in ultra-relativistic collisions of elementary particles or strings to improve the determination of parameters appearing in the effective-one-body approach to the relativistic two-body problem. This includes profiting from a newly-discovered on-shell construction of gravitational amplitudes from gauge-theory amplitudes; (iv) connect properties of the gravitational wave spectrum at low frequencies to recent developments in soft-graviton theorems at sub- and sub-sub-leading level, including predictions for gravitational memory, BMS asymptotic symmetries, and logarithmic enhancements; (v) explore various consequences of modified gravity theories for the LIGO/Virgo discoveries.

The participants who would like to present a poster are kindly invited to send an email with the title and a short abstract to alice.bernamonti@unifuit before May 22, specifying for which week of the workshop. Since a limited number of panels is available, the organizers will select the posters shortly after the deadline.
