Gravitational-wave propagation constraints on the dynamical Barbero--Immirzi field from GWTC-3 dark sirens
Zhi-Fu Gao, Hui Wang, Luiz Carlos Garcia de Andrade
The Barbero--Immirzi (BI) parameter, originally a constant in the Holst term of first-order gravity, can be promoted to a dynamical scalar field coupled to torsion in Einste…

Dynamical Barbero--Immirzi field coupled to quintessence: gravitational-wave propagation constraints and next-generation forecasts
Zhi-Fu Gao, Hui Wang, Luiz Carlos Garcia de Andrade +3
We investigate the imprints of a dynamical Barbero--Immirzi (BI) field coupled to a quintessence scalar field on gravitational-wave (GW) propagation. In the framework of…
