Abstract

We study supersymmetric solutions of matter-coupled F(4) gauged supergravity in the forms of $A d S_{2} \times S^{3}$ $AdS_2\times S^3$ - and $A d S_{3} \times S^{2}$ $AdS_3\times S^2$ -sliced domain walls with a non-vanishing two-form field from the supergravity multiplet. These two types of solutions holographically describe conformal line and surface defects within five-dimensional $N = 2$ $$N=2$$ SCFTs, respectively. In the case of $S O (3) \times S O (3)$ $SO(3)\times SO(3)$ gauge group obtained by coupling F(4) supergravity to three vector multiplets, we find charged domain wall solutions describing holographic RG flows between two supersymmetric $A d S_{6}$ $$AdS_6$$ vacua with a running two-form field supporting the line and surface defects. For a particular case of one vector multiplet with $S O (3) \times U (1)$ $SO(3)\times U(1)$ gauge group, we find solutions describing RG flows from an $A d S_{6}$ vacuum to physically acceptable singular geometries in the presence of defects. This class of solutions can be uplifted to type IIB theory using a consistent truncation obtained from SO(5, 5) exceptional field theory with half-maximal structures.
