Observables and amplitudes for spinning particles and black holes

Abstract: We develop a general formalism for computing classical observables for relativistic scattering of spinning particles, directly from on-shell amplitudes. We then apply this formalism to minimally coupled Einstein-gravity amplitudes for the scattering of massive spin 1/2 and spin 1 particles with a massive scalar, constructed using the double copy. In doing so we reproduce recent results at first post-Minkowskian order for the scattering of spinning black holes, through quadrupolar order in the spin-multipole ex… Show more

“…Subsequently, using and extending a formalism for extracting classical observables from on-shell amplitudes developed by Kosower, Maybee and O'Connell [52], the generalization to spinning particles was considered by Maybee et al [53]. It was shown in [53] through O(a 2 ), and then by Ochirov et al in [54] through O(a ∞ ) for both spins, that the arbitrary-spin tree amplitudes from [40,42,43] lead (by a well-motivated procedure) to the covariant scattering holonomy results for genericspin binary BHs at O(G 1 a ∞ ) derived by one of the authors in [15], matching at O(G 1 a 1 ) results of Bini and Damour [10].…”

A scalar-probe limit of the same genericspin scattering holonomy, namely the O(G 1 a ∞ ) impulse (change in momentum) for a generic (weakly deflected) unbound geodesic in the Kerr spacetime, has also been produced from an elegant double copy of the amplitude for the analogous electromagnetic case, a test charge in the " √ Kerr " electromagnetic field in flat spacetime, by Arkani-Hamed, Huang and O'Connell [55]; see also [56].…”

“…Extracting classical gravitational physics from quantum field theories has a long history [2][3][4]. More recently the modern on-shell scattering amplitudes program has provided a number of tools that can be used to greatly simplify calculations of gravitational quantities, notably the KLT relations and the BCJ double copy [5][6][7][8][9], as well as those related specifically to classical observables [10][11][12]. While the original aim of the double copy program was to simplify loop computations in gravity, it has found many uses in classical gravity, from metric reconstruction [13][14][15][16][17][18][19][20] to gravitational wave physics [21][22][23][24].…”
