We consider the transverse-momentum (q_T) distribution of Standard Model Higgs bosons produced by gluon fusion in hadron collisions. At small q_T (q_T<<m_H, m_H being the mass of the Higgs boson), we resum the logarithmically-enhanced…

A sextet quark sector of QCD, together with the sextet higgs mechanism, would produce a major change in the strong interaction above the electroweak scale. This change may already be evident in Cosmic Ray physics and, if so, dramatic…
