Outputs wave function renormalisation for SUSY parameters and gauge beta functions up to 2 loops. Also calculates and outputs a. IO parameters: RH leptons, LH leptons, LH quarks, RH downs, RH ups, H1 and H2 respectively. g^Li_Lj = m_{ij} for LH fields g^Ei_Ej = m_{ji} for RH fields

Two-loop pieces

void MssmSusy::diagQuarkBasis	(	DoubleMatrix &	vdl,
		DoubleMatrix &	vdr,
		DoubleMatrix &	vul,
		DoubleMatrix &	vur
	)		const

Rotates to quark mass basis, returning the mixing matrices defined as = vul vur^+, = vdl vdr^+ All matrices should be 3 by 3

void MssmSusy::getMasses	(	QedQcd &	r,

	)		const

Outputs one-loop anomlous dimensions gii given matrix inputs. for RH leptons, LH leptons, LH quarks, RH downs, RH ups, H1 and H2 respectively. Note that we use the convention (for matrices in terms of gamma's): gamma^Li_Lj = M_ij for LH fields and gamma^Rj_Ri = M_ij for RH fields (since they are really the complex conjugates of the RH fields). a should already be defined.

void MssmSusy::getQuarkMixedYukawas	(	const QedQcd &	r,
		const DoubleMatrix &	CKM,
		int	mix,
		double	vev
	)

Defines mixed Yukawa matrices from data input in form of CKM matrix and r, vev. If mix=2, all mixing is in down sector mix=1, all mixing is in up sector

Calculates three-loop anomalous dimensions in the dominant third family approximation and adds them

powers of gauge couplings

< 1/(16 pi^2)^3

< 6 Zeta(3)

For calculational brevity NB Change notation to that of J&J hep-ph/0408128 (Y->Y^T , etc)

Everything gets the (1/16pi^2)^3 factor at the bottom

	)		const

Outputs two-loop anomlous dimensions gii given matrix inputs. for RH leptons, LH leptons, LH quarks, RH downs, RH ups, H1 and H2 respectively.

void MssmSusy::quarkMixing	(	const DoubleMatrix &	CKM,

This turns diagonal Yukawa couplings at MZ into CKM mixed ones Takes diagonal quark Yukawa matrices and mixes them up according to the CKM matrix assuming: mix=2, all mixing is in down sector mix=1, all mixing is in up sector
