The Cygnus X region is known as the richest star-forming region within a few kpc and is home to many particle accelerators such as supernova remnants, pulsar wind nebulae or massive star clusters. The abundance of accelerators and the ambient conditions make Cygnus X a natural laboratory for studying the life cycle of the cosmic-ray. The correlation between radio and gamma radiation from this region has been examined, where emissions from both leptonic and hadronic processes have been taken into account. In doing so, the transport and loss mechanism in Cygnus is investigated, such that the resulting neutrino spectrum is derived. By considering the rigidity differences between electrons and protons and a steady state description of a plasma, the total source of the high energy CRs has been calculated as generally as possible. Since only minute pieces of information about local processes in Cygnus are available and small inhomogeneities vanish at larger scales, a spherically symmetric and spatially homogeneous vicinity is assumed. Moreover, the influence of continuous losses and catastrophic losses due to diffusion and advection is investigated in order to provide a realistic picture of Cygnus-X.
