Distribution of the number of synthetic YMSCs detectable by LHAASO in ROI1 (upper row) and ROI2 (bottom row) for the three diffusion coefficients considered in this analysis: Kolmogorov, Kraichnan and Bohm (from left to right). We label a YMSC as detected if the significance of its emission at 100 TeV is larger than 5σ. Colour filled (striped) histograms correspond to the scenarios where WRs are (are not) included in the mock stellar populations.
