Impact of QED backgrounds on light-by-light scattering measurements at and colliders
K. I. Beloborodov, T. A. Kharlamova, V. I. Telnov
The process of elastic scattering of photons (, light-by-light scattering) has attracted significant interest in recent years as a loop-induced process sensitive to all c…

The branching fraction measurements of decay into and final states
KEDR Collaboration, V. V. Anashin, O. V. Anchugov +95
We present measurements of the branching fractions for the meson decays into the and final states, based on data collected with the KEDR detector at the VEPP-4…

New measurement of D0 and D+ meson masses with the KEDR detector
KEDR Collaboration, V. V. Anashin, O. V. Anchugov +117
Using the 4.9 pb statistics collected at the peak of the resonance with the KEDR detector at the VEPP-4M electron-positron collider, we measured the masses of the…
