Extended Reissner-Nordstr\"om solutions sourced by dynamical torsion

Understand

We find a new exact vacuum solution in the framework of the Poincar\'e Gauge field theory with massive torsion.

• In this model, torsion operates as an independent field and introduces corrections to the vacuum structure present in General Relativity.
• The new static and spherically symmetric configuration shows a Reissner-Nordstr\"om-like geometry characterized by a spin charge.
• It extends the known massless torsion solution to the massive case.
