Abstract: MAGIS-100 is a macroscopic
‘Quantum-Sensor’, based on a 100-meter light-pulse atom
interferometer, being built at Fermilab by an international
collaboration, in search of the “dark” sector of the universe
(“dark” matter and energy) and...
The Institute for Advanced Study requires that all adult
visitors, collaborators, conference and on-campus seminar attendees
and outside vendors coming to the Institute are required to have
completed a COVID-19 vaccination and booster in order to...
Abstract: Over the last few years, much has
been learned about the types of special functions that Feynman
diagrams give rise to near integer dimensions. In this talk, I
further explore this question by studying a new infinite class of
Abstract: The amplitudes for soft gauge
boson emission are related to the non-radiative amplitudes via soft
theorem. The soft limit of gauge theories and perturbative gravity
are surprisingly similar despite the different gauge structures.
Abstract: In this talk I will focus on
light dark matter particles, with a mass between 1 MeV and a few
GeV. These particles can annihilate or decay into electron-positron
pairs which can upscatter the low-energy fields in our Galaxy and
