Comparison of the Standard Theory Predictions of M_W and Sin^2 theta^lept_eff with their Experimental Values
arXiv:1211.1864 · doi:10.1103/PhysRevD.87.037501
Abstract
Assuming that the recently discovered particle at LHC is the Standard Theory (ST) Higgs Boson, we compare the ST predictions of M_W and Sin^2 theta^lept_eff with the experimental values of these basic observables. While the Sin^2 theta^lept_eff prediction is in excellent agreement with its experimental value, that of M_W shows a 1.33 sigma deviation. Implications of these comparisons for possible future developments at LHC and a future GigaZ linear collider are briefly discussed. It is also pointed out that these comparisons are consistent with the conjecture that the newly discovered particle is indeed the ST Higgs boson.
