The total cross-sections for -nucleon scattering have been measured. A test has been made of the muon number conservation law. A limit of 2.4 GeV is found the mass of the “Georgi-Glashow type” heavy lepton 相似文献

There are many speculations that there exist quarks Q considerably heavier than the charmed quark. Their Q states will display a far richer spectrum of monochromatic photon and hadron transitions than charmonium. The most important features of this spectrum — in particular, its dependence on the mass of Q — are outlined. 相似文献

The last few years have been witness to a proliferation of new results concerning heavy exotic hadrons.Experimentally, many new signals have been discovered that could be pointing towards the existence of tetraquarks,pentaquarks, and other exotic configurations of quarks and gluons. Theoretically, advances in lattice field theory techniques place us at the cusp of understanding complex coupled-channel phenomena, modelling grows more sophisticated, and effective field theories are being applied to an ever greater range of situations. It is thus an opportune time to evaluate the status of the field. In the following, a series of high priority experimental and theoretical issues concerning heavy exotic hadrons is presented. 相似文献
