Abstract:

Differential cross sections dσ/dPT for prompt charm meson production in pp̄ collisions at √s=1.96 TeV were measured. The measured differential cross sections are higher than the theoretical predictions by about 100% at low pT and 50% at high pT. However, they are compatible within uncertainties. The models also underestimate Β meson productions at √s=1.8 TeV by similar factors [2,4,5].

Abstract:

We present a measurement of the mass difference m(Ds+) -m(D+), where both the Ds+ and D+ are reconstructed in the φπ+ decay channel. This measurement uses 11.6 pb-1 of data collected by CDF II using the new displaced-track trigger. The mass difference is found to be m(D s+)-m(D+) = 99.41±0.38(stat) ±0.21(syst) MeV/c2. copy; 2003 The American Physical Society.

Identification of cosmic rays using drift chamber hit timing

Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment 506:1-2 (2003) 110-118

Abstract:

Identification of cosmic rays was discussed. Drift chamber hit timing method was used. The central outer tracker (COT) tracks as cosmic rays were studied and their direction of propagation and time of incidence were also measured.
