We introduce a new class of twisted sinc-correlation Schell-model (TSCSM) beams and analyze the statistical characteristics such novel sources during propagation. Several typical examples are given to specifically explore distribution twist effect spectral density degree coherence (DOC). It is shown that irradiance profile light intensity always rotates 90 degree. With appropriate field adjustment, DOC would be diverse. can exhibit unidirectional or non-unidirectional rotation Besides, factor make spot show tendency split. And beam width length also have an impact on this splitting phenomenon density.
