Limit on the production of a low-mass vector boson in e + e − → U γ , U → e + e − with the KLOE experiment

Physics Letters B, 2015
AbstractThe existence of a new force beyond the Standard Model is compelling because it could explain several striking astrophysical observations which fail standard interpretations. We searched for the light vector mediator of this dark force, the U boson, with the KLOE detector at the DAΦNE e+e− collider.

QCD predictions for energy moments in e+e− single arm experiments

Physics Letters B, 1982
Abstract We show that a new class of large infrared corrections in QCD can be easily observable by measuring the moments of the jets energy deposited in a calorimeter in single cone experiments.

The interference between virtual photon and 1−− charmonium in e+e− experiment

Physics Letters B, 2004
e+e- Experiments producing charmonium are reviewed. It is found that the contribution of the continuum amplitude via virtual photon was neglected in almost all the experiments and the channels analyzed. It is shown that the contribution of the continuum part may affect the final results significantly in psi(2S) and psi(3770) decays, while the ...

DEPFET pixel detector for future e-e+ experiments

Nuclear and Particle Physics Proceedings, 2016
AbstractThe DEPFET Collaboration develops highly granular, ultra-thin pixel detectors for outstanding vertex reconstruction at future e+e- collider experiments. A DEPFET sensor provides, simultaneously, position sensitive detector capabilities and in-pixel amplification by the integration of a field effect transistor on a fully depleted silicon bulk ...
