SUMMARY:Seminar by Yushi Mura (KEK)
DESCRIPTION:Title: ‘UV completion of extended Higgs models via the confinement of SU(2) gauge’ \nSpeaker: Yushi Mura (KEK) \nVenue & Time: Red Room / 15:00 \nAbstract: The extended Higgs sectors are often introduced to explain phenomena beyond the standard model. On the other hand\, the existence of multiple scalar fields may cause the Landau pole below the Planck scale. Therefore\, those models should be replaced by more fundamental theory at high energies. In this talk\, we consider an asymptotic-free SU(2) gauge theory as a UV-completion of the extended Higgs models and assume they are the consequence of confinement of the gauge theory. We find that particle contents of various extended Higgs sectors previously proposed are deduced by each charge assignment of flavor symmetry of the fundamental fermions of the SU(2) gauge symmetry.

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
