LHC diboson excesses as an evidence for a heavy WW resonance | | B.A. Arbuzov

8 Oct 2015 | | Abstract: | Recently reported diboson excesses at LHC are interpreted to be connected
with heavy $WW$ resonance with weak isotopic spin 2. The resonance appears due
to the wouldbe anomalous triple interaction of the weak bosons, which is
defined by well-known coupling constant $lambda$. We obtain estimates for the
effect, which qualitatively agree with ATLAS data. Effects are predicted in
inclusive production of $W^+W^+, W^+ (Z,gamma), W^+ W^-, (Z,gamma)
(Z,gamma), W^- (Z,gamma), W^-W^-$ resonances with $M_R simeq 2,TeV$, which
could be reliably checked at the upgraded LHC with $sqrt{s},=,13 TeV$. In
the framework of an approach to the spontaneous generation of of the triple
anomalous interaction its coupling constant is estimated to be $lambda =
-,0.017pm 0.005$ in an agreement with existing restrictions. | | Source: | arXiv, 1510.2312 | | Services: | Forum | Review | PDF | Favorites | |
