Stable matter of 4 th generation : hidden in the Universe and close to detection ?

Stable neutrino and U quark of 4th generation are excluded neither by experimental data, nor by astrophysical constraints. Moreover, excess of stable Ū quarks in the Universe can lead to an exciting composite nuclearinteracting form of dark matter, which can even dominate in large scale structure formation. 1 Stable pieces of 4th generation matter The… CONTINUE READING
