◆ anti()

virtual void o2scl::part::anti ( part ap)
virtual

This sets the m, g, ms, inc_rest_mass and non_interacting fields of ap equal to that of the current object. If inc_rest_mass is true, then it sets

\[ \mu_{\mathrm{anti}} = - \mu \qquad\mathrm{and}\qquad \nu_{\mathrm{anti}} = - \nu \]

and if inc_rest_mass is false, it sets

\[ \mu_{\mathrm{anti}} = - \mu - 2 m \qquad\mathrm{and}\qquad \nu_{\mathrm{anti}} = - \nu - 2 m \]
