Globular clusters display an anticorrelation between the fraction of the first generation of stars ( N (G1) / N (tot)) and the slope of the present-day mass function of the clusters ( α pd ), which is particularly significant for massive clusters. In the framework of the binary-mediated collision scenario for the formation of the second-generation stars in globular clusters, we test the e ff ect of a varying stellar initial mass function (IMF) of the G1 stars on the ( N (G1) / N (tot)) − α pd…
