Linac-ring type colliders: Second way to TeV scale

Main parameters and the physics search potentials of the linac-ring type lepton-hadron and photon-hadron colliders are discussed. The THERA (TESLA on HERA), “NLC”-LHC and “CLIC”-VLHC proposals are considered.PACS: 13.60.-r Photon and charged-lepton interactions with hadrons – 29.90.+r Other topics in elementary-particle and nuclear physics experimental methods and instrumentation

Fourth standard model family neutrino at future linear colliders

It is known that flavor democracy favors the existence of the fourth standard model (SM) family. In order to give nonzero masses for the first three-family fermions flavor democracy has to be slightly broken. A parametrization for democracy breaking, which gives the correct values for fundamental fermion masses and, at the same time, predicts quark and lepton Cabibbo-Kobayashi-Maskawa (CKM) matrices in a good agreement with the experimental data, is proposed. The pair productions of the fourth SM family Dirac
