Diffraction

Friday 7 May 2010, 08:00 → 18:00 Europe/Zurich

TH Theory Conference Room (CERN)

Michelangelo Mangano (CERN), Rainer Schicker

LHC physics day dedicated to diffraction. The focus of the day will be tools for the modeling of diffraction in MB events at the LHC, and the review of diffractive observables for the 2010-11 run of the LHC.

To join the diffraction-lhc@cern.ch mailing list, which will be used in the future for diffraction-related communications, please go to http://simba3.web.cern.ch/simba3/SelfSubscription.aspx?groupName=diffraction-lhc

The meeting will be broadcast via EVO (see below for the connection URL, and the "Video Services" item on the left menu bar)

For those attending, information on accommodation, access to CERN and laptop registration is available from http://cern.ch/lpcc/visits

11:35 → 12:10 MC modelling of hard diffraction at HERA - LHC

I want to review how hard diffraction with diffractive parton densities is included in MCs at HERA and how the final states are described. It will also include pQCD models of the diffractive exchange. One issue is, how the final state is build and how the diffractive part is merged to the inclusive cross section. Then also some ideas will be discussed, how this can be used for simulation of hard diffraction at the LHC.

14:10 → 14:40 What is needed from the MC side for diffractive measurements ? (CMS)

I want to discuss, which measurements are planned for the near future and what is needed in terms of MCs. An important point will be what is needed to estimate the model uncertainties: issues of the parton showers, hadronization etc.
