Technicoloured signatures

Scalarless theories with extended technicolour have several new consequences at energies of a few hundred GeV, which will be accessible in future accelerators. A large class of such theories have several (60, 116 or 132) pseudo-Nambu-Goldstone bosons with masses from a few GeV to ∼300 GeV. These bosons are classified and their model-independent properties are discussed. Their most important properties are: (i) they can be singly produced; (ii) their decays give rise to some exotic final states involving jets; (iii) more than 90% of them are coloured. Therefore, they can be produced in the future overlinepp and pp machines, predominantly via 2-gluon collisions.
