Conservative Dynamics of Binary Systems at Fourth Post-Minkowskian Order in the Large-eccentricity Expansion
Christoph Dlapa, Gregor Kälin, Zhengwen Liu +1
We compute the conservative dynamics of non-spinning binaries at fourth Post-Minkowskian order in the large-eccentricity limit, including both potential and radiation-reaction tail…
From Boundary Data to Bound States III: Radiative Effects
Gihyuk Cho, Gregor Kälin, Rafael A. Porto
We extend the "boundary-to-bound" (B2B) correspondence to incorporate radiative as well as conservative radiation-reaction effects. We start by deriving a map between the total cha…
EuCAPT White Paper: Opportunities and Challenges for Theoretical Astroparticle Physics in the Next Decade
R. Alves Batista, M. A. Amin, G. Barenboim +134
Astroparticle physics is undergoing a profound transformation, due to a series of extraordinary new results, such as the discovery of high-energy cosmic neutrinos with IceCube, the…
Hidden-Sector Neutrinos and Freeze-In Leptogenesis
Ina Flood, Rafael Porto, Jane Schlesinger +2
Sterile neutrinos at the GeV scale can resolve several outstanding problems of the Standard Model (SM), such as the source of neutrino masses and the origin of the baryon asymmetry…
Dynamics of Binary Systems to Fourth Post-Minkowskian Order from the Effective Field Theory Approach
Christoph Dlapa, Gregor Kälin, Zhengwen Liu +1
We present the contribution from potential interactions to the dynamics of non-spinning binaries to fourth Post-Minkowskian (4PM) order. This is achieved by computing the scatterin…
Gravitational radiation from inspiralling compact objects: Spin-spin effects completed at the next-to-leading post-Newtonian order
Gihyuk Cho, Brian Pardo, Rafael A. Porto
Using the gravitational potential and source multipole moments bilinear in the spins, first computed to next-to-leading order (NLO) in the post-Newtonian (PN) expansion within the…
