Tentative List

Scientific Program

Scientific program template media:JPos_v4.xlsx

a) long talk (35+5) introductory plenary session, one talk for each of the following: - Two photon exchange - DVCS - Beyond Standard Model - Dark Matter search - Low energy applications - High energy positron beams - Low energy positron sources

b) short talk (25+5) general plenary session, 3-4 talks for each of the sub-topics: -Interference Physics -Charged Current Physics -Test of the Standard Model -Positron Applications -Positron Source and Beam Physics

c) parallel discussion (two 2-hr sessions), session organizers should identify program e.g.: -Specific or technical talks more appropriate for individual sub-topics -Opportunity for round-table discussion and consensus

d) poster session (90 min w/ coffee break), 3-4 poster are requested for each of the sub-topics: -Interference Physics -Charged Current Physics -Test of the Standard Model -Positron Applications -Positron Source and Beam Physics
