Abstract
The contributions of [Formula: see text]-boson predicted by the chiral color symmetry of quarks to the differential dijet cross-sections in pp-collisions at the large hadron collider (LHC) are calculated and analyzed in dependence on two free parameters of the model, the [Formula: see text] mass [Formula: see text] and mixing angle [Formula: see text]. The exclusion and consistency [Formula: see text] regions imposed by the ATLAS and CMS data on dijet cross-sections are found. Using the CT10 (MSTW2008) parton distribution function (PDF) set we show that the [Formula: see text]-boson for [Formula: see text], i.e. the axigluon, with the masses [Formula: see text] TeV and [Formula: see text] TeV is excluded at the probability level of 95% by the ATLAS and CMS dijet data, respectively. For the other values of [Formula: see text] the exclusion limits are more stringent. The [Formula: see text] regions consistent with these data at CL = 68% and CL = 90% are also found.
