## Prompt

TOP QUARK — QCD RADIATIVE CORRECTION
m_t(tree) = v- = 129.45 GeV. Apply 1-loop QCD correction: m_t(pole) = m_t(MS)*(1 + 4*alpha_s(m_t)/3pi + ...). Using alpha_s(m_Z) = 0.1179, run to m_t scale. Compute m_t(pole). Compare to PDG 172.57 GeV. Assess whether algebraic correction or RG running closes the -25% tree gap. Show all steps. #SuperGrokTOE #TopQuark #QCDcorrections
