Oblique corrections from triplet quarks. (English) Zbl 07690595

Summary: We present general formulas for the oblique-correction parameters \(S\), \(T\), \(U\), \(V\), \(W\), and \(X\) in an extension of the Standard Model having arbitrary numbers of singlet, doublet, and triplet quarks with electric charges \(-4/3\), \(-1/3\), 2/3, and 5/3 that mix with the standard quarks of the same charge.
