Hi Everyone, This week we meet at 1 PM Eastern time on Thursday, July 30, for our weekly LQS meeting. Dial-in is 510-665-5437, passcode 7336. We'll take another stab at discussing Boris Kayser's recent preprint, "Leptogenesis and its Electromagentic Variant", http://arxiv.org/abs/0907.2664. This paper discusses how the baryon-antibaryon asymmetry could have occurred through standard leptogenesis and also considers a new version of leptogenesis via CP violation in electromagnetic decays. The meeting website is: http://dmtpc.mit.edu/MaKaC/conferenceDisplay.py?confId=191 The paper is available on the meeting page and from arxiv.org. Hope you can join us. Thanks much, --Ray
