Abstract: A foremost task in understanding the nature of the燲(3872)爄nvolves the discrimination of the two-quark and multiquark configurations. In this work, we propose a method to probe the short-distance component of the燲(3872)燽y measuring the ratio between the燘c爏emileptonic and nonleptonic decays into the燲(3872). We demonstrate that if the燲(3872)爌roduction mechanism is through the燾痗燾omponent, the ratios would be universal and could be reliably predicted in theory. Measurements of these ratios at LHC and the next-generation electron-positron colliders are capable of validating/invalidating this production mechanism and providing deeper insights into the nature of the燲(3872).
