摘要:

考虑到目前Tevatron实验对第四族夸克质量的限制,预计第四族夸克的质量将大于顶夸克。由于它们预期的大质量,它们可能具有与标准模型的三个家族的夸克不同的动力学。在质心能量为10 TeV和14 TeV的大型强子对撞机上,通过反常产生子过程gq_i-->t'(其中q_i=u,c)研究了第四族上型夸克t'的共振产生.这种过程的签名内的SM衰变模式进行了讨论。当\sqrt{s} =10 TeV,L_int=100 pb^(-1)时,对反常耦合的灵敏度κ/Λ=0.1 TeV^(-1)。

英文摘要:

Considering the present limits on the masses of fourth family quarks from the Tevatron experiments, the fourth family quarks are expected to have mass larger than the top quark. Due to their expected large mass they could have different dynamics than the quarks of three families of the Standard Model. The resonant production of the fourth family up type quark t' has been studied via anomalous production subprocess gq_i-->t' (where q_i=u,c) at the LHC with the center of mass energy 10 TeV and 14 TeV. The signatures of such process are discussed within the SM decay modes. The sensitivity to anomalous coupling κ/Λ=0.1 TeV^(-1) can be reached at \sqrt{s}=10 TeV and L_int=100 pb^(-1).
