Belinfante Symmetrization from Metric-Affine Conservation Laws: Hypermomentum as the Improvement Term -- The Cases of QED and QCD
Damianos Iosifidis
The paper derives the Belinfante–Rosenfeld symmetrization of the energy‑momentum tensor from metric‑affine conservation laws, showing that the divergence of the hypermomentum curre…

Gravitational waves in Cubic Metric-Affine Gravity
Sebastian Bahamonde, Jorge Gigante Valcarcel, José M. M. Senovilla
The paper presents exact pp‑wave solutions in a cubic metric‑affine gravity model that include dynamical torsion and nonmetricity, leading to an additional scalar polarization mode…
