Dear Tipp2014, I just tried to submit an abstract, but cannot as I do not have a CERN account, and do not use personal social media accounts for business.
Many US physicists will not have CERN accounts, and almost certainly most US industrial partners and technical folks will not as well. The login presents a real barrier for non-European detector folks in submitting abstracts (this may be part of the reason you may have gotten fewer than expected, if I can guess one reason for the recent delaying of the deadline). I couldn't find an easy way to get a CERN `lightweight' account- would it be possible to get explicit instructions on how to submit an abstract from the US? I think that making the TIPP page a little more user-friendly for abstract submission would also help. Many thanks, Henry Frisch Prof. of Physics, Enrico Fermi Institute
