| 英文摘要 | In this paper we reexamine how to utilize the previous proposed color-octet axial-vector boson Z(C) to explain the 3: 4 sigma anomaly of t (t) over bar forward-backward (FB) asymmetry A(FB) for m(t (t) over bar) > 450 GeV observed by CDF. Our numerical results indicate that the best-fit parameters are g(A)(q) = 0: 07, g(A)(Q) 3, and M(C) 440 GeV, which are obtained by fitting the mass dependent AFB and total cross section data provided by a recent CDF measurement. Here g(A)(q) (g(A)(Q)) and MC are the axial couplings among Z(C) with the first two (the third) generation quarks, and Z(C) mass, respectively. We also calculate one-side forward-backward asymmetry AOFB for top and bottom quark pair production at the LHC, focusing on the new contributions from Z(C). Our studies show that AOFB can be utilized to measure the properties of new particle Z(C). |
