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?

Haha, you're trying to read a lot, indeed. Let me just guess that "Fabio knows" almost certainly doesn't mean "Fabiola knows". The former is male, the latter is female. It could be Fabio Maltoni see e.g. or someone else. – LuboŇ° Motl Dec 15 '11 at 6:32
Sorry if this sounds curt, but the answer is "Not yet." (and this was written at the end of 2015.) – adavid Dec 29 '15 at 22:29
I think this is a dated question. He was probably referring to what ended up identified as the Higgs in 2012… – anna v Apr 30 at 13:50
