"xsec_diff_mjet" of "Measurement of the jet mass distribution and top quark mass in hadronic decays of boosted top quarks in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

The particle-level $\mathrm{t}\overline{\mathrm{t}}$ differential cross section in the fiducial region as a function of the XCone-jet mass.在 fiducial区域（fiducial region）内，粒子级（particle-level）顶夸克-反顶夸克对（$tar{t}$）的微分截面，其以XCone喷注（XCone-jet）质量为变量。
