O2scl : Class List

template<class fp_t = double>
class part_tl

Public Functions

inline part_tl(const part_tl &p)

Copy constructor.

inline part_tl &operator=(const part_tl &p)

Copy construction with operator=()

inline part_tl(fp_t mass = 0.0, fp_t dof = 0.0)

Make a particle of mass mass and degeneracy dof.

inline virtual ~part_tl()
inline virtual void init(fp_t mass, fp_t dof)

Set the mass mass and degeneracy dof.

inline virtual void anti(part_tl &ax)

Make ap an anti-particle with the same mass and degeneracy.

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

inline virtual const char *type()

Return string denoting type (“part_tl”)
