Single Top as Window on Heavy Quarks and Other New Physics

Figure 2

Single top cross-section in the 𝑡-channel versus centre-of-mass energy, comparing the existing measurements at Tevatron and LHC with the QCD expectations computed at NLO with MCFM in the 5-flavour scheme [24] and at NLO + NNLL [25]. The error band (width of the curve) includes the uncertainty on the top mass, the PDF uncertainty estimated according to the HEPDATA recommendations [26], and the factorization and renormalization scales changed coherently by a factor two up and down.
