Query: Braneworld cosmology in $f(R,T)$ gravity   Braneworld scenarios consider our observable universe as a brane embedded in
a 5D space, named bulk. In this work, I derive the field equations of a
braneworld model in a generalized theory of gravitation, namely $f(R,T)$
gravity, with $R$ and $T$, representing the Ricci scalar and the trace of the
energy-momentum tensor, respectively. The cosmological parameters obtained from
this approach are in agreement with recent constraints from Supernovae Ia data
combined with baryon acoustic oscillations and cosmic microwave background
observations, favouring such an alternative description of the universe
dynamics.
