Tubular Initial Conditions and Ridge Formation

Figure 4

The integrated spectra with the tube-like ICs. The top row demonstrates the case of 1 displaced tube with the Gaussian background (iii): left: at 𝑟₁=0.55𝑅, right: at 𝑟₁=1.04𝑅. The 2nd row corresponds to the case of 1 displaced tube with the Woods-Saxon background (vii): left: at 𝑟_𝑖=0.5𝑅, right: at 𝑟_𝑖=1.1𝑅. The 3rd row is related to the IC with 3 tubes and the Gaussian background (iv): left: 𝐫_𝑖=(0,0),(−1,3.6),(−1,−3.6) fm, right: 𝐫_𝑖=(0,5.6),(−1,3.6),(−1,−3.6) fm. The 4th row is related to the Gaussian background: left: 4 tubes (v), right: 10 tubes (vi).
