Renormalizability via extensions of the basis-vector framework

Establish whether the theory becomes renormalizable by either extending the basis-vector description in 2(2n+1)-dimensional spaces to string-based basis vectors or by extending those basis vectors to odd-dimensional spaces of the form 2(2n+1)+1.

Background

The paper proposes a new formulation of internal spaces using Clifford-odd (fermionic) and Clifford-even (bosonic) basis vectors. The authors raise the question of renormalizability within this framework and suggest two possible routes—string-like extensions or dimensional extensions to odd-dimensional spaces—as potential resolutions.

Determining renormalizability is crucial for quantum consistency and predictive power of the framework beyond perturbative toy examples provided in the text.

There remain questions to be answered: iv.a. Can the theory achieve renormalizability by extending the “basis vectors” in 2(2n+1)-dimensional spaces with the ”basis vectors” of strings, or by extending the “basis vectors” in 2(2n+1)-dimensional spaces to odd-dimensional, 2(2n + 1) + 1, spaces?
