a Momentum-resolved electronic spectra and single-particle band-structure along the high-symmetry lines of the bulk Brillouin zone (the upleft inset). The momentum-resolved electronic spectra are in bright yellow color. The single-particle band-structure is represented by the red dashed curves. b Fermi arcs on the (001) surface. The blue and red dots, W1 and W2, represent the projected Weyl points with positive and negative chirality, respectively. The three white arrows indicate the Fermi arcs. c Bulk Weyl cones along the direction connecting the Weyl points W1 and W2 in b. Distribution of the Berry curvature around the Weyl points W1 (d) and W2 (e) in the kxy plane.
