Hi Marcel, others, and Z' aficionados,
I have a question that keeps puzzling me. Am I correct in noticing a sudden increased interest on Z' models? This puzzles me since I was under the impression these models have been excluded to almost 3TeV by direct searches! See: http://arxiv.org/abs/1405.4123 (assuming SM couplings). In fact, the limits were already past 1 TeV back in 2011!
Do these results somehow not apply to some LHCb results (e.g. Bs → μμ)? If so, why? Are there other motivations than significantly weaker couplings for them to not show up in direct searches?
Just a few itches I had to scratch ...
Cheers,
PS: Do we also have a page like this? https://twiki.cern.ch/twiki/bin/view/AtlasPublic/ExoticsPublicResults

Dear colleagues,
at the request of some of our PhD/master students I will arrange an informal lecture/discussion session on Completing the standard model with right-handed neutrinos and Z'
Time: Monday May 11, 14.00-16.00 (or how long it takes) Place: H331
Everyone interested is welcome, basic knowledge of QFT theory and the standard model will be assumed.
