Function Documentation

diagonalize_sfermions_2x2()

double flexiblesusy::sfermions::diagonalize_sfermions_2x2	(	const Mass_data &	pars,
		double &	msf1,
		double &	msf2
	)

returns mixing angle and sets (squared) mass eigenvalues

Obtains 2 x 2 mass matrix using input parameters in first argument and diagonalises it. Fills the second argument with the (squared) mass eigenvalues and returns the mixing angle.
