NNLO initial-state corrections to $e^{+} e^{-} \to μ^{+} μ^{-} γ$

Yizhou Fang, Sara Gündogdu, Sophie Kollatzsch +3

We present initial-state corrections to $e^{+} e^{-} \to μ^{+} μ^{-} γ$ at next-to-next-to-leading-order in QED for several experimentally motivated scenarios up to a few GeV. We include…

Radiative pion-pair production in disperon QED

Yizhou Fang, Sophie Kollatzsch, Adrian Signer +1

Based on the previously developed disperon QED method for incorporating data input into loop processes in Monte Carlo codes, we calculate $ee \to π π γ$ at NLO and include the pion vec…

Low-energy $e^{+} e^{-} \to γ γ$ at NNLO in QED

Tim Engel, Marco Rocco, Adrian Signer +1

We present a fully differential computation of $e^{+} e^{-} \to γ γ$ at next-to-next-to-leading order in QED. The process has been implemented into McMule, completing its set of next-t…

Disperon QED

Yizhou Fang, Sophie Kollatzsch, Marco Rocco +3

We present disperon QED, a method to deal with data input in loop processes in Monte Carlo codes. It relies on dispersion relations, automated tools such as OpenLoops, effective fi…

A Beamdump Facility at Jefferson Lab

Patrick Achenbach, Andrei Afanasev, Pawel Ambrozewicz +47

This White Paper is exploring the potential of intense secondary muon, neutrino, and (hypothetical) light dark matter beams produced in interactions of high-intensity electron beam…

Parity violation in Møller scattering within low-energy effective field theory

Sophie Kollatzsch, Daniel Moreno, David Radic +1

We include electroweak effects in Moller scattering at low energies in an effective field theory approach and compute the left-right parity-violating asymmetry. The calculation usi…
