Abstract

We calculate the bound state properties of stoponium using lattice formulation of nonrelativistic effective field theory for stop which is moving nonrelativistically in the rest frame of stoponium. Our calculation method is similar to that employed in lattice nonrelativistic quantum chromodynamics (NRQCD) studies for charmonium and bottomonium. Using 16³\ifmmode×\else\texttimes\fi256 quenched lattice gauge field configurations at a^\ensuremath-1=50(1) GeV, we obtain the stoponium mass and the lattice matrix element which is related to the wave function at the origin for the 1S state and find that the lattice |R_1S(0)|²/M_1S³ is 3.5--4 larger than that from a potential model calculation for 200 GeV\ensuremath≤M_1S\ensuremath≤800 GeV.
