First Search for Quirks at the LHC with FASER / R.M.Abraham, S.Dmitrievsky, Yu.Gornushkin, S.Vasina, [a.o.]. – Text : electronic // Physical Review Letters. – 2026. – Vol. 137, No. 18. – P. 181802. – URL: https://doi.org/10.1103/z156-xk5y. – Bibliogr.: 36.

We present the first LHC search for quirks, particles with standard model and QCD-like infracolor (IC) interactions. The analysis uses data collected in 2022–2024 by FASER, with a 186 fb*−*1 integrated luminosity of proton-proton collisions at a center-of-mass energy *%s= 13.6 TeV. Scintillator charge and timing information are used to search for slow pairs of quirks with no QCD color and electric charge 1. No events are seen in this nearly background-free search, resulting in the first exclusion of quirks with masses above the weak scale for IC confinement scales in the broad range of 300 eV < Λ < 100 keV.
