    • The enhanced sensitivity of the deuteron binding energy to the strong quark mass is explained by four factors 5: (1) deuteron is the shallow level which may be eliminated by small variation of the binding potential; (2) there is strong cancellation between (Formula presented)-meson and (Formula presented)-meson contributions into nucleon-nucleon interaction (Walecka model), therefore, a minor variation of (Formula presented)-meson mass leads to a significant change in the strong potential; (3) the (Formula presented) meson contains valence s and anti-s quarks which give large contribution to its mass; (4) (Formula presented)-meson energy level is repelled down due to mixing with close (Formula presented) state. Some strange mass contribution also comes from the proton mass
