QCD Laplace Sum Rules and the $\mathrm{\Pi }(1300)$ Resonance

A global fit to the shape of the first QCD Laplace sum rule exhibiting sensitivity to pion-resonance [$\mathrm{\Pi }(1300)$] parameters is performed, leading to predictions for the pion-resonance mass and decay constant. This fit leads to predictions of $M_{\pi }=1.15\pm 0.15GeV$ for the pion-resonance mass, and $F_{\pi }^2=(4.5\pm 2.1)\mathrm{.}(f_{\pi }^2{m}_{\pi }^4\mathrm{/}{M}_{\pi }^4)$ for the pion-resonance decay constant.
