In the recent Higgs seminar at 73:38 Guido Tonelli the spokesman for CMS, makes a mistake and refers to a Z-prime in a context that would imply that they see them frequently. He swiftly backpedals amid the general hilarity of the concept. However a few seconds later he remarks that "There is something behind this", implying that there is a reason why he might have Z-primes on his mind and he says "Fabio knows" referring to Fabiola Gianotti who leads the ATLAS team.
Can we expect some announcement regarding a Z-prime boson? Does anyone have more information?
