Excited quarks production at FCC and SppC pp colliders

İngilizce (OpenAlex)

Potential discovery, observation and exclusion limits of excited [Formula: see text] and [Formula: see text] quarks with gamma[Formula: see text]jet final state are researched at the multi-TeV scale colliders, FCC and S[Formula: see text]C in this paper. Both colliders, FCC and S[Formula: see text]C, show that excited [Formula: see text] and [Formula: see text] quarks could be discovered up to 42.1 TeV and 55.2 TeV for [Formula: see text], 30.3 TeV and 39.4 TeV for [Formula: see text] and 42.3 TeV and 55.5 TeV mass values for degenerate case [Formula: see text], respectively. The determination of the excited quarks compositeness scale is examined, which will be up to multi-PeV level. Besides these analyses, free parameters ([Formula: see text], [Formula: see text] and [Formula: see text]) are scanned from around 0.1 up to 1 that show excited quark could be discovered at dozens of TeV with even coupling constants under 0.1.
