Scalar field collapse in Gauss-Bonnet gravity

Understand

We consider a "Scalar-Einstein-Gauss-Bonnet" theory in four dimension, where the scalar field couples non minimally with the Gauss-Bonnet (GB) term.

• This coupling with the scalar field ensures the non topological character of the GB term.
• In this scenario, we examine the possibility for collapsing of the scalar field.
• Our result reveals that such a collapse is possible in the presence of Gauss-Bonnet gravity for suitable choices of parametric regions.
