Novel corrections to the momentum sum rule for nuclear structure functions
Physics Letters B, 2022 We address novel features of deep inelastic lepton scattering on nuclei at small Bjorken variable xBj. In this regime the lepton-nuclear cross section involves the interference between the standard lepton-quark scattering amplitude for the deep inelastic

I=3 Three-Pion Scattering Amplitude from Lattice QCD. [PDF]
Physical Review Letters, 2019 We analyze the spectrum of two- and three-pion states of maximal isospin obtained recently for isosymmetric QCD with pion mass M≈200 MeV in Hörz and Hanlon, [Phys. Rev. Lett. 123, 142002 (2019)PRLTAO0031-900710.1103/PhysRevLett.123.142002].

Classical Gravitational Spinning-Spinless Scattering at O(G^{2}S^{∞}). [PDF]
Physical Review Letters, 2022 Making use of the recently derived, all-spin, opposite-helicity Compton amplitude, we calculate the classical gravitational scattering amplitude for one spinning and one spinless object at O(G^{2}) and all orders in spin.

International Journal of Adaptive Control and Signal Processing, EarlyView., 2023 Summary In this contribution, we propose a detailed study of interpolation‐based data‐driven methods that are of relevance in the model reduction and also in the systems and control communities. The data are given by samples of the transfer function of the underlying (unknown) model, that is, we analyze frequency‐response data.

Scattering amplitude recursion relations in Batalin-Vilkovisky–quantizable theories [PDF]
Physical Review D, 2019 Tree-level scattering amplitudes in Yang-Mills theory satisfy a recursion relation due to Berends and Giele which yields e.g., the famous Parke-Taylor formula for maximally helicity violating amplitudes. We show that the origin of this recursion relation

Searching for Kerr in the 2PM amplitude [PDF]
Journal of High Energy Physics, 2022 The classical scattering of spinning objects is well described by the spinor-helicity formalism for heavy particles. Using these variables, we derive spurious-pole-free, all-spin opposite-helicity Compton amplitudes (factorizing on physical poles to the ...

Real part of pp scattering amplitude in additive quark model at LHC energies [PDF]
The European Physical Journal C, 2018 Elastic pp scattering at LHC energies is treated in additive quark model together with Pomeron exchange theory. The obtained results are compared with the new experimental data on the ratio of real to imaginary part of the scattering amplitude at the ...

Determination of the scattering amplitude [PDF]
Communications in Mathematical Physics, 1984 Within the range of elastic scattering of two particles the unitarity equation can be formulated as an integral equation for the phase of the analytic scattering amplitude if the cross-section is given. Since the publications of \textit{R. G. Newton} [Determination of the amplitude from the differential cross-section by unitarity, J. Math. Phys.

Scattering Amplitudes, the Tail Effect, and Conservative Binary Dynamics at O(G^{4}). [PDF]
Physical Review Letters, 2021 We complete the calculation of conservative two-body scattering dynamics at fourth post-Minkowskian order, i.e., O(G^{4}) and all orders in velocity, including radiative contributions corresponding to the tail effect in general relativity. As in previous
