Four-dimensional regular black strings in bilocal gravity

CR Muniz, HR Christiansen, MS Cunha, J Furtado - Annals of Physics, 2022 - Elsevier
In this paper, we obtain a static black string solution for a bilocal gravitational source in 3+ 1
dimensions. The solution is regular at the origin and tends asymptotically to the ordinary …
