Radiative corrections are crucial for modern high-precision physics experiments, and are an
area of active research in the experimental and theoretical community. Here we provide an …

The dynamical evolution of nucleus-nucleus collisions is described by a transport equation
of the Uehling-Uhlenbeck type. Our model evolves phase-space distribution functions for …

Recent anomalies in the decays of B mesons and the Higgs boson provide hints towards
lepton flavor (universality) violating physics beyond the Standard Model. We observe that …

A low-background sample of 10 300 events has been collected for the decay mode K+→ π+
e+ e− by experiment E865 at the Brookhaven Alternating Gradient Synchrotron. The …

The conversion decays φ→ ηe+ e− and η→ γe+ e− were studied by the SND detector using
φ-meson production in e+ e−-annihilation at VEPP-2M collider. The branching ratios of …

We have recalculated the Mikaelian and Smith radiative corrections to the Dalitz decay π
0→ e+ e-γ beyond the soft-photon approximation, ie over the whole range of the Dalitz plot …

We calculate the radiative corrections to the π 0→ γ e+ e− decay over the whole range of the
Dalitz plot, with no restrictions on the radiative photon energy. The corrections are found to …

E865 at the Brookhaven National Laboratory AGS collected about 70 000 K e 3+ events to
measure the K e 3+ branching ratio relative to the observed K+→ π+ π 0, K+→ π 0 μ+ ν, and …

We present results of an experiment in which approximately 500 events of the decay K+→
π+ e+ e− were observed. We have measured the branching ratio for K π e e+ to be …

The NA62 experiment collected a large sample of charged kaon decays in 2007 with a
highly efficient trigger for decays into electrons. A measurement of the π 0 electromagnetic …
