Özet:

  A minimal fermion-scalar preonic model containing two fermionic preons and one scalar preon is proposed. This scheme allows prevention of the occurrence of undesired SM-level particles, namely leptons and quarks with unusual electric charges. Similar to the previous FS models, color-octet leptons and color-sextet quarks, which are expected to have masses much lower than the compositeness scale, are predicted. Observation of these particles could provide first indications of preonic models. The FCC/SppC pp option will give an opportunity to probe mq6 m q 6 up to 48/75 TeV and ml8 m l 8 up to 15/27 TeV within 1 year of operation at nominal luminosity. FCC/SppC based ep and μ μ p colliders will essentially enlarge the covered mass region, namely me8 m e 8 up to 23/27 TeV and mμ8 m μ 8 up to 68/80 TeV.
