Colleagues, We are looking forward to another productive ALCPG Workshop at Fermilab, October 22-16. We want to update you on the plans for the workshop, particularly with the organization of the physics working groups. A set of four groups based on physics signatures has been created, and the conveners have initiated their planning for the respective sessions. These groups are: I - b/c Separation and Tau Tagging (Conveners: Frank Paige (BNL) , Jay Hubisz (FNAL) , Andrei Nomerotski (Oxford), Marco Battaglia (UC Berkeley/LBNL), Ronald Lipton (Fermilab)) II - Jet and Photon Energy Measurements (Conveners: Ray Frey (Oregon) , Steve Magill (Argonne), Frank Petriello (Wisconsin), Alexei Raspereza (MPI Munich), Tim Tait (Argonne)) III - Missing Energy (Convener: Jim Alexander (Cornell), Carola Berger (SLAC) , Konstantin Matchev (Florida) , Tao Han (Wisconsin) , Graham Wilson (Kansas) , Bill Morse (BNL)) IV - Charged Particle Momentum Measurement, V0 Reconstruction, and Identification of Stable Charged Particles (Conveners: Henry Band (Wisconsin) , Ayres Freitas (Zurich), Tim Nelson (SLAC), Bruce Schumm (UC Santa Cruz), Shufang Su (Univ Arizona)) Each of these groups will explore the physics enabled by their specific signature of focus, and quantify the physics reach as a function of performance. The designated contacts for these groups are I - Andrei Nomerotski ([log in to unmask]) II - Ray Frey ([log in to unmask]) III - Jim Alexander ([log in to unmask]) IV - Bruce Schumm ([log in to unmask]) Based on the advanced discussions and planning by the conveners, we are anticipating this format to be stimulating and productive for both theorists and experimentalists. We encourage you to communicate with the conveners with your ideas, and requests for time.
