Modern Determination of Pion and Kaon Fragmentation Functions from SIA and High-Precision COMPASS SIDIS Multiplicities
HAPS Collaboration, Maryam Soleymaninia, Hamzeh Khanpour +4
We present a combined determination of charged-pion and charged-kaon fragmentation functions (FFs), denoted HAPS-PiFF1.0 and HAPS-KaFF1.0, at next-to-leading order (NLO) and within…
Revisiting Unidentified Charged-Hadron Fragmentation Functions with Modern COMPASS SIDIS Multiplicities
HAPS Collaboration, Maryam Soleymaninia, Hamzeh Khanpour +4
We present \texttt{HAPS-hFF1.0}, a new global QCD analysis of unidentified charged-hadron fragmentation functions (FFs) using single-inclusive electron-positron annihilation (SIA)…
Parity violation in atoms: neutrino-mediated long range forces and finite nuclear size
Mikhail Gorchtein, Hubert Spiesberger
We consider neutral-current parity-violating interactions in an atom mediated by the exchange of a neutrino-antineutrino pair. We explicitly account for the nuclear finite size enc…
Box at Low Energy
Balma Duch, Pere Masjuan, Hubert Spiesberger
We calculate the 1-loop box-graph correction to electron-quark scattering at low energy and low momentum transfer. Both electron and quark masses are kept non-zero. From our…
