The results reinforce the conclusions of the CSN4 GLV on 2001-2003
2005 update on CSN4 productivity
• (CSN4 ISI papers)/FTE = 1.55
• Papers 2005: 1104 CSN4 out of 2135 INFN: > 50%
• (CSN4 authors)/(all authors) = 0.54
• Scientific events organized: 46 CSN4 out of 120 INFN: 38%
• Presentations at international conferences: 606 CSN4 out of 1509 INFN: 40%
• CERN: ~2 papers/FTE/year (only research, visitor program)
Quality (2001-2003):
• the paper selected for the VTR (110 out of about 2400) all turned out to be among the 10 topcited in their field
More evaluations: the IS’s are evaluated every 3 years by anonymous international referees, which affects the distribution of resources

Statistics
• 9 weeks (2/5-30/6), 73 selected participants + 4 + 6 (~150 apps)
• 77 = 37 Europe + 35 North America + 5 Others (25% Italians)
• Average stay: 19 days
High scientific and organizational standards
• Participants
• Seminars + colloquia + joint conference with Johns Hopkins Workshop (30th)
• Stimulating scientific atmosphere, (very!) lively discussions
• Positive feedback from the participants (come-backs), papers are being produced
Benefits for Italian theoretical physics:
• Top level international implant in the fertile Italian context
• Participants from TO, LNGS, RM1, RM2, TS, FI, MIB, PD, PI, LE, SA
• Other Italian activities of participants
Minor issue: reimbursements (Italians)
New directions BSM in Field and String Theory

Montecarlo Workshop
3-4 short workshops in 2006- in preparation for LHC (27-28/02, 22-24/06, 23-25/10)
A framework for integration (including pedagogical efforts) and interactions of
• Theorists interested in LHC physics (Montecarlo + Models)
• Experimentalists (mostly ATLAS + CMS)
taking advantage of the vast experience of the Italian MC community (COJET, HERWIG, MC@NLO, CKKW, ALPGEN, ...) and the traditional attention paid by the Italian BSM community to the experiment
Test of Models for LHC physics involve:
• prediction for production cross section of new particles and their decays into SM particles (τ < thad)
• fragmentation, hadronization, more decays (τ > thad)
• trigger and signals in the detector
• comparison with SM background

Topics:
• Shower MC: development, interface with tree level and NLO calculations
• Matrix elements: automatic computation of complex microscopic amplitudes (multilegs, loops)
• BSM: Signals and BKGS
• Experimental studies: detector simulations and calibration with SM physics
Stimulates
• interactions over the whole range of expertise (string-experimentalist!)
• the MC community to implement a variety of options currently studied by the BSM community in their codes
• the BSM community to focus on signatures
