DESCRIPTION:Speakers: Mr. MORIKAWA\, Okuto (Kyushu University)\nIt is beli
eved that the two-dimensional massless $\\mathcal{N}=2$ Wess--Zumino model
becomes the $\\mathcal{N}=2$ SCFT in the IR limit. We examine this theore
tical conjecture of the Landau--Ginzburg (LG) description of the $\\mathca
l{N}=2$ SCFT by numerical simulations on the basis of a supersymmetric-inv
ariant momentum-cutoff regularization. We study one or two supermultiplets
with various superpotentials. From a two-point correlation function in th
e IR region\, we measure the central charge\, which is consistent with the
conjectured LG description of the ADE minimal models. Our result supports
the theoretical conjecture and\, at the same time\, indicates a possible
computational method of correlation functions in the $\\mathcal{N}=2$ SCFT
from the LG description.\n\nhttps://conference-indico.kek.jp:443/indico/e
