Abstract

In this paper, we propose a new test to the cosmic distance duality relation (CDDR), DL=DA(1+z)2D_L=D_A(1+z)^2, where DLD_L and DAD_A are the luminosity and angular diameter distances, respectively. The data used correspond to 61 Type Ia Supernova luminosity distances and YSZEYXY_{SZE}-Y_X measurements of 61 galaxy clusters obtained by the {\it Planck} mission and the deep XMM-Newton X-ray data, where YSZEY_{SZE} is the integrated comptonization parameter obtained via Sunyaev-Zel'dovich effect observations and YXY_X is the X-ray counterpart. More precisely, we use the YSZEDA2/CXSZEYXY_{SZE}D_{A}^{2}/C_{XSZE}Y_X scaling-relation and a deformed CDDR, such as DL/DA(1+z)2=η(z)D_L/D_A(1+z)^2=\eta(z), to verify if η(z)\eta(z) is compatible with the unity. Two η(z)\eta(z) functions are used, namely, η(z)=1+η0z\eta(z)=1+\eta_0 z and η(z)=1+η0z/(1+z)\eta(z)=1+\eta_0 z /(1+z). { We obtain that the CDDR validity (η0=0\eta_0=0) is verified within 1.5σ\approx 1.5\sigma c.l. for both η(z)\eta(z) functions.}.
