27 | | As a generic framework, the four Vector-Like states X (Q=5/3), T (2/3), B (-1/3) and Y (-4/3) are introduced as new spin 1/2 class members. Each class defines a specific top partner with a fixed electric charge, without any assumption on the other quantum numbers. The model file [attachment:VLQ.fr], loaded in Mathematica with [attachment:VLQ.nb], is designed to allow for a straightforward extension to additional vector-like fermions, simply by adding the new particles to the corresponding class (F~~[5], F[6], F[7] and F[8]~~ for X-, T-, B- and Y-type quarks, respectively). Particles embedded in larger SU(2) representations may also be introduced under new classes, following the same model-independent prescription. |
