TL;DR
This paper investigates the Schr"odinger functional coupling in a lattice Yang-Mills theory with an improved bosonic spinor field, modeling QCD with negative two light flavors, as a computationally efficient test case for coupling scaling.
Contribution
It introduces a study of the Schr"odinger functional coupling in a lattice QCD-like theory with negative two flavors, providing a new testing ground for coupling scaling analysis.
Findings
Demonstrates the feasibility of studying coupling scaling in this theory.
Provides data on the Schr"odinger functional coupling for the model.
Establishes a basis for future non-perturbative studies in similar theories.
Abstract
We study the Schr\"odinger functional coupling for lattice Yang-Mills theory coupled to an improved bosonic spinor field, which corresponds to QCD with minus two light flavors. This theory serves as a less costly testcase than QCD for the scaling of the coupling.
