Detailed Description

Contains all supersymmetric RPC-MSSM parameters.

Constructor & Destructor Documentation

softsusy::MssmSusy::MssmSusy ( )

Constructor fills object with zeroes by default

softsusy::MssmSusy::MssmSusy ( const DoubleMatrix u,
const DoubleMatrix d,
const DoubleMatrix e,
const DoubleVector v,
double  m,
double  tb,
double  h 
)

Constructor given Yukawa matrices u,d,e, gauge couplings v, mu parameter=m, tan beta=tb, renormalisation scale MU, number of loops in RG evolution l and thresholds parameter t

void softsusy::MssmSusy::anomalousDimension ( DoubleMatrix gEE,
DoubleMatrix gLL,
DoubleMatrix gQQ,
DoubleMatrix gUU,
DoubleMatrix gDD,
DoubleVector dg,
double &  gH1H1,
double &  gH2H2,
sBrevity a 
) const

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

Constants for gauge running

Constants not set yet

sBrevity a contains all of the shortcutted matrices etc;

For calculational brevity

1 loop contributions:

2 loop contributions:

MssmSusy softsusy::MssmSusy::beta ( sBrevity a) const

Outputs derivatives (DRbar scheme) in the form of ds. a contains the matrices calculated that are handy for computation. W= LL Y^E H1 ER + QL Y^D H1 DR + QL Y^U H2 UR + smu H2 H1 is the superpotential. Consistent with Allanach, Dedes, Dreiner hep-ph/9902251 and Barger, Berger and Ohmann hep-ph/9209232, 9311269 EXCEPT for the sign of smu, which is opposite. These equations are also valid for W= - LL Y^E H1 ER - QL Y^D H1 DR + QL Y^U H2 UR + smu H2 H1, the new SOFTSUSY convention

Wave function renormalisations: convention for g**(i, j) is that i is the LOWER index and j the upper in our paper hep-ph/9902251

keep this option in order to interface with RPVSUSY

To keep this a const function

contain derivatives of up, down quarks and leptons

mu parameter derivatives

RGEs of SUSY parameters

Following is from hep-ph/9308335: scalar H anomalous dimensions (as opposed to the chiral superfield one - see hep-ph/0111209). Additional contribution from Feynman gauge running at two-loops of tan beta: we need this to link up with BPMZ: hep-ph/0112251

1/(16 pi^2)^2

One-loop RGEs in Feynman gauge

Two-loop pieces

Contains all susy derivatives:

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

Rotates to quark mass basis, returning the mixing matrices defined as $(Y_U)_{diag}$ = vul $Y_U$ vur^+, $(Y_D)_{diag}$ = vdl $Y_D$ vdr^+ All matrices should be 3 by 3

const DoubleVector softsusy::MssmSusy::display ( ) const

Calculate beta functions of SUSY preserving parameters of RPC MSSM Returns all parameters as elements of a vector

void softsusy::MssmSusy::getMasses ( QedQcd r,
double  vev 
) const

outputs object QedQcd & r valid at 1 GeV from SUSY data at mt, from diagonal elements of Yukawa couplings and Higgs VEV vev.

void softsusy::MssmSusy::getOneLpAnom ( DoubleMatrix gEE,
DoubleMatrix gLL,
DoubleMatrix gQQ,
DoubleMatrix gDD,
DoubleMatrix gUU,
double &  gH1H1,
double &  gH2H2,
sBrevity a 
) 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.

For calculational brevity

void softsusy::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

void softsusy::MssmSusy::getTwoLpAnom ( DoubleMatrix gEE,
DoubleMatrix gLL,
DoubleMatrix gQQ,
DoubleMatrix gDD,
DoubleMatrix gUU,
double &  gH1H1,
double &  gH2H2,
sBrevity a 
) 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. 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 softsusy::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

Sets diagonal Yukawa couplings according to data in QedQcd input and Higgs VEV parameter vev= $v_1^2+v_2^2$
