| Manuscript Title: BCVEGPY: An event generator for hadronic production of the Bc meson. | ||
| Authors: C.-H. Chang, C. Driouichi, P. Eerola, X.-G. Wu | ||
| Program title: BCVEGPY | ||
| Catalogue identifier: ADTJ | ||
| Journal reference: Comput. Phys. Commun. 159(2004)192 | ||
| Programming language: Fortran 77. | ||
| Computer: Any computer with a Fortran 77 compiler. | ||
| Operating system: Windows, Linux, UNIX. | ||
| Keywords: Bc meson, Hadronic production, Event generator, Particle physics, Elementary, Quantum Chromodynamics. | ||
| Classification: 11.5. | ||
Nature of problem: Hadronic production of Bc meson. | ||
Solution method: Improved helicity-approach to the amplitude and symmetries of the amplitude itself have been used to compact the program so as to save as much cpu as possible. The code with option can generate weighted and un-weighted events. For jet hadronization, an interface to PYTHIA is provided. | ||
Restrictions: The hadronic production of the Bc meson in the S-wave, states i.e., pseudo-scalar state (1S0) and vector state (3S1) are included by the 'complete calculation' approach. The hadronic production of Bc meson in P-wave states has not been implemented into BCVEGPY yet. | ||
Running time: It depends on which option one chooses to match PYTHIA when generating the Bc events. Typically, if IDWTUP = 1, then it takes about 20 hours on a 1.8 GHz Intel P4-processor machine to generate 1000 events; however if IDWTUP = 3, it only takes about 40 minutes to generate 106 events. |
