SUMMARY:Old Journal Club: 'Threshold production of heavy top quarks: QCD and the Higgs boson'
DESCRIPTION:Sergio Rodríguez (IFT) will present “Threshold production of heavy top quarks: QCD and the Higgs boson” by Matthew J. Strassler and Michael E. Peskin. \nAbstract:  \nWe calculate the threshold cross section for 𝑒+𝑒−→tt¯ to leading-logarithmic order in QCD\, using a nonrelativistic approximation suggested by Fadin and Khoze. We study the mass range 100≤𝑚𝑡≤250 GeV\, and show that the cross section is an excellent measure of α𝑠 for the lower portion of the mass range\, while for a heavier top quark it is sensitive to the mass and couplings of the Higgs boson. We argue that a precise determination of 𝑚𝑡 and a measurement of Γ𝑡 are possible. We also show that nonperturbative effects are small\, confirming that the tt¯ threshold is a detailed perturbative test of the standard model. \nMore info: https://journals.aps.org/prd/pdf/10.1103/PhysRevD.43.1500
