Kavli Affiliate: Igor Moskalenko | First 5 Authors: Chris Karwin, Simona Murgia, Igor Moskalenko, Sean Fillingham, Anne-Katherine Burns | Summary: An excess $gamma$-ray signal toward the outer halo of M31 has recently been reported. Although other explanations are plausible, the possibility that it arises from dark matter (DM) is valid. In this work we interpret […]

Kavli Affiliate: Tom Melia | First 5 Authors: Tom Melia, Sridip Pal, , , | Summary: We establish formulae for the asymptotic growth (with respect to the scaling dimension) of the number of operators in effective field theory, or equivalently the number of $S$-matrix elements, in arbitrary spacetime dimensions and with generic field content. This […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Maulik Parikh, Frank Wilczek, George Zahariade, , | Summary: We develop a formalism to calculate the response of a model gravitational wave detector to a quantized gravitational field. Coupling a detector to a quantum field induces stochastic fluctuations ("noise") in the length of the detector arm. The […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Maulik Parikh, Frank Wilczek, George Zahariade, , | Summary: For the purpose of analyzing observed phenomena, it has been convenient, and thus far sufficient, to regard gravity as subject to the deterministic principles of classical physics, with the gravitational field obeying Newton’s law or Einstein’s equations. Here […]
