Abstract
The Cygnus region, which contains massive molecular and atomic clouds and young stars, is a promising Galactic neutrino source candidate. Cosmic rays transport in the region can produce neutrinos and $\gamma$-rays. Using ten years of track events detected by the IceCube Neutrino Observatory, we conduct searches for neutrino signals from the Cygnus region with a template method. Four templates, including the CO map, HI map, uniform map, and 2D Gaussian map, are used in this study. No significant emissions are found. We set upper limits for each template, with the resulting upper limit for the CO map being $\rm d\phi_\nu/\rm dE_\nu=6.25\times10^{-17}(E_{\nu}/100\mathrm{TeV})^{-3}\mathrm{TeV}^{-1}\mathrm{cm}^{-2}\mathrm{s}^{-1}$.
