LHCPhenoNet annual meeting

2 Dec 2013, 14:00 → 5 Dec 2013, 18:30 Europe/Zurich

4/3-006 - TH Conference Room (CERN)

German Rodrigo (CSIC), Michelangelo Mangano (CERN), S. Moch (UHH)

2013 meeting of the LHCPhenoNet network. The meeting starts on Monday at 2pm, and finishes by Thursday afternoon. Everyone is welcome to stay through Friday for collaborative work etc.

A set of rooms (both singles and doubles, which could be cheaper for students or convenient for those of you visiting with a companion) have been pre-booked at the CERN Hostel, covering the period Sunday (check-in) through Friday (check-out). To reserve them, you must request michelle.connor@cern.ch (do NOT contact the Hostel, they will refuse your booking), indicating the nights of your stay.

To register your laptop, follow the link:
http://registerVisitorComputer
and provide Elena Gianolio (PH department, AGS group) as contact person.

The meeting will be broadcast via Vidyo.

16:30 Visit to CMS

Safety information for the visitors: closed, flat or block-heeled shoes are required for the site visits (duck board) and helmets will be provided; Access to underground areas is forbidden to pregnant women and to persons equipped with any of the following: pacemaker, defibrillator, electronic medicine dispenser, hearing aid, metal implant. The bus will be waiting on the Road Bohr close to the Foyer for departing to CMS at 16h30. It takes about 1/2 hour to get from Meyrin to Point 5 in Cessy. Four CMS guides are confirmed. For security reasons, not more than 24 visitors are admitted to the cavern (12 persons/guide). Upon arrival at Point 5, two guides will take down the group of 24 persons, the other two guides will give a tour on the surface. Then, the groups will be swapped. This means that unfortunately the visit is limited to 48 persons. Please, check that you reserved a place at registration (see attached file)

16:40 Documenting through activity diagrams in VINCIA

Speaker: Juan Jose Lopez Villarejo (CEA/IRFU,Centre d'etude de Saclay Gif-sur-Yvette (FR))

Slides 2013Dec-CERN-LopezVillarejo.pdf

VINCIA is a Monte Carlo parton shower, which aims to provide a fast and precise simulation of high-energy proton-proton collisions at LHC. It is a plug-in to PYTHIA 8, currently under development. It features Markov multiplicative multi-leg matching to exact matrix-elements.
There is a considerable knowledge gap between the algorithm as explained in the papers and the actual workings of the code. In VINCIA, we aim to document the code through high-level activity diagrams (workflows) in order to bridge this gap. These diagrams will be generated automatically from special comments written alongside the c++ code by the developers. This is akin to Doxygen documentation, but incorporates 'dynamical' information on the execution flow.
