Nucleon and delta sigma-terms

Nucleon and delta sigma-terms

We evaluate nucleon and delta sigma-terms and obtain the results 43 MeV < sigmaN < 49 MeV and 28 MeV < <FONT FACE=Symbol>sD</FONT> < 32 MeV, depending on the coupling constants used, which are compatible with values extracted from experiment and produced by other groups. We show that the decay <FONT FACE=Symbol>D ® p</FONT>N explains the relation <FONT FACE=Symbol>sD</FONT> < sigmaN.
