Hi Suvayu, et al,
Indeed, the Z' is hot recently as it can be related to signatures of B_s,d --> mumu, B-->K*mumu, and R_K=(B->Kmumu/B->Kee).
As was discussed in Moriond, all of these measurements are being fitted with a modified C9 Wilson coefficient, which would then perhaps point to New Physics of a Z' (or leptoquarks, or perhaps even many other things).
In fact, we made a public news item on this on the Nikhef website on March 20,
In order to be consistent with other measuremnts, the mass range of such a Z' would be in the range of 2 - 7 TeV or so. Also its couplings should be non-standard, in particular to describe the lepton flavour vioalting R_K ratio.
There are two events coming up:
1. Jan-Willen van Holten from Nikhef-theory is going to discuss the theory aspects of the Z', as he was asked by the NIkhef theory community who triggered on the Z' news. (see Jan Willem announcement)
2. Altmannshofer (one of the speakers presenting the Z' results at Moriond) will come to Nikhef for a colloquium on the friday after our workshop. We are thinking to organise a little workshop with Robert around this talk.
cheers,
- Marcel
