Choudhury Beautiful mirrors and precision electroweak data 2002 21 .pdf application/pdf 8491 817 79 The Standard Model (SM) with a light Higgs boson provides a very good description of the precision electroweak observable data coming from the LEP, SLD In this article, we shall concentrate upon the most obvious of such a possible deviation [2], namely the forward-backward asymmetry (AbF B) of the b-quark, the measurement • In general, due to the large mixing in the bottom sector and the fact that the righthanded mirror quarks carry non-trivial weak charges, a potentially large correction leads to a better fit to the data whenever the new quarks are relatively light and the Higgs quark bound to 250 GeV leads to an optimal value of the Higgs mass of about 850 GeV. Any new quark [37], with a mass below or about 250 GeV, as preferred in the model On the other hand, the model with non-standard mirror quark doublets leads to ./cache/work_edalj6ne25hzvmppic73zqejhu.pdf ./txt/work_edalj6ne25hzvmppic73zqejhu.txt
