Abstract

Coulomb and charge-symmetry breaking effects in the $^{3}$ He ground state within the dressed dibaryon model developed recently for $2 N$ and $3 N$ forces are examined in detail. Particular attention has been paid to the Coulomb displacement energy $Δ E_{C} = E_{B} (^{3} H) - E_{B} (^{3} He)$ and rms charge radii of $^{3}$ H and $^{3}$ He. A new scalar $3 N$ force between the third nucleon a $d iba r y o ni s f o u n d t o b e v er y im p or t an t f or a cor r ec t d escr i pt i o n o f t h e C o u l o mb e n er g y an d r m sc ha r g er a d i u s in$ ^3 $H e .
