Two-Loop Four-Fermion Scattering Amplitude in QED
R. Bonciani, A. Broggio, S. Di Vita +9
We present the analytic evaluation of the two-loop corrections to the amplitude for the scattering of four fermions in Quantum Electrodynamics, , with…
The three-loop singlet contribution to the massless axial-vector quark form factor
T. Gehrmann, A. Primo
We compute the three-loop corrections to the quark axial vector form factor in massless QCD, focusing on the pure-singlet contributions where the axial vector current couples to a…
Theory for muon-electron scattering @ 10ppm: A report of the MUonE theory initiative
P. Banerjee, C. M. Carloni Calame, M. Chiesa +17
We review the current status of the theory predictions for elastic - scattering, describing the recent activities and future plans of the theory initiative related to the pr…
Frequency-dependent time decay of Schrödinger flows
L. Fanelli, V. Felli, M. Fontelos +1
We show that the presence of negative eigenvalues in the spectrum of the angular component of an electromagnetic Schrödinger hamiltonian generically produces a lack of the cla…
Time decay of scaling invariant Schroedinger equations on the plane
L. Fanelli, V. Felli, M. Fontelos +1
We prove the sharp L^1-L^{\infty} time-decay estimate for the 2D-Schroedinger equation with a general family of scaling critical electromagnetic potentials.
