Dependence of hadronic properties on quark masses and constraints on their cosmological variation
Dependence of hadronic properties on quark masses and constraints on their cosmological variation
We follow our previous paper on possible cosmological variation of weak scale (quark masses) and strong scale, inspired by data on cosmological variation of the electromagnetic fine structure constant from distant quasar (QSO) absorption spectra. In this work we identify the {\em strange quark mass} $m_s$ as the most important …
