چکیده

We report a measurement of the exclusive e+e- -->D(*)+/-D*-/+ cross section as a function of center-of-mass energy near the D(*)+/-D*-/+ threshold with initial-state radiation. A partial reconstruction technique is used to increase the efficiency and to suppress background. The analysis is based on a data sample collected with the Belle detector with an integrated luminosity of 547.8 fb(-1).

The t¯t Threshold and Machine Parameters at the NLC

One of the problems in the design of a high energy e + e − linear collider is the distribution of the luminosity as a function of real collision energy, dL/dE, due to initial state radiation, beamstrahlung, and the energy spread of the collider. These effects smear a sharp feature in the cross section of e + e − → hadrons such as the t ¯ t threshold into a flatter structure. This study reviews ...

At the DAΦNE-II workshop a session was devoted to the prospects of measuring the hadronic cross section at the new DAΦNE. The session included six papers, two theoretical and four experimental ones. The theory treatises, one on the muon anomaly and the other on measuring the hadronic cross section using initial state radiation at e + e − colliders, set the background for the four experimental d...
