The post-fit \(m_{cc}\) distribution summed over all signal regions after subtracting backgrounds, leaving only the \(VH(\rightarrow c{\bar{c}})\), \(VW(\rightarrow cq)\) and \(VZ(\rightarrow c{\bar{c}})\) processes, for events with a one c-tag and b two c-tags. The red filled histogram corresponds to the \(VH, H\rightarrow c{\bar{c}}\) signal for the fitted value of \(\mu _{VH(c{\bar{c}})} = -9\), while the open red histogram corresponds to the signal expected at the 95% CL upper limit on \(\mu _{VH(c{\bar{c}})}~(\mu _{VH(c{\bar{c}})}=26)\). The hatched band shows the uncertainty of the fitted background
