Imagine to discover a new fourth family of leptons at the Large Hadron Collider (LHC) but no signs of an associated fourth family of quarks. What would that imply? An intriguing possibility is that the new fermions needed to compensate for the new leptons gauge anomalies simultaneously address the big hierarchy problem of the Standard Model. A natural way to accomplish such a scenario is to...

By constructing and employing global, unique fit for the fourth generation mass mixing matrix within the Standard model with the 4th generation quarks b' and t', we examine CP-violating phenomena in flavor changing neutral current processes t -> cX; b'-> sX, b'-> bX,t'-> cX, and t'-> tX, with X=Z,H,gamma,g and discuss their effects on the global CPV picture.

45. Extra families seek friendship with heavy Higgs and inert doublet

We study the possibility of the existence of extra fermion families and an extra Higgs doublet. We find that requiring the extra Higgs doublet to be inert leaves ample space for three extra families and marginally accommodates four, allowing for mirror fermion families and a dark matter candidate at the same time. The emerging scenario is very predictive: it consists of a heavy Standard Model...
