CHORUS Collaboration Meeting, Ishigaki, Japan/ 07-08 April 2003

MC productions and data/MC

• JETTA and specific generators

• Eficass and CHANT

• Data/MC comparison for emulsion events

• Summary and plans

Ilya Tsukerman/ CERN-EP and ITEP Moscow (presented by J. Panman)

JETTA and specific generators

• WHINTER: non-official large production done CC, NC and charm events were simulated and

reconstructed

• ASTRA: non-official large production done Ds and Ds

* events were simulated and reconstructed

• QEGEN: small technical bug fixed by F. Di Capua

Official production files were not affected.

• MCDIS: tests well advanced, ported to CVS

• JETTA improvements: -- June 2003 Details: IT talk at Feb. 2003 emulsion workshop

Eficass and CHANT

• New CHANT summ (setup4, all events,20 loops) -- done

See plots and tables for data/MC comparison

• New CHANT DST/summ (the same) -- In progress CHANT-02-03-06; SUMM with FUJI for Netscan simulation

• CHANT (setup3, all, 20 loops) -- In progress

• Eficass (setup4, CC DIS, 120 loops) -- June 2003

• CHANT (setup4, CC DIS, 120 loops) -- July 2003

Existing simulated DIS events

Existing simulated QE events

Fraction of 1 events

Energy measured in CALO

Leading muon momentum

Leading muon angle w.r.t. direction

Primary vertex Y position

Primary vertex Z position

Summary and plans

• WHINTER and ASTRA: full production done

• New SUMM created, data/MC well advanced DATA/MC in general agree well; just a few problems

• CHANT setup3, new DST for setup4: running SUMM will have FUJI, needed for Netscan

• CHANT: 120 loops for CC setup4 -- July 03
