Detailed Description

Class for calculating Jacobian fine-tuning measure.

This class provides methods for calculating the Jacobian fine-tuning measure as defined in arXiv:1312.4150, $\Delta_J = | \partial O_j / \partial p_i |$, where $\{O_j\}$ refers to a set of observables and $\{p_i\}$ to a set of model parameters, and $ \partial O_j / \partial p_i$ is the Jacobian for the transformation from the observables to the parameters.

The sets $\{O_j\}$ and $\{p_i\}$ used depend on the global flags softsusy::Z3 and softsusy::SoftHiggsOut. If softsusy::SoftHiggsOut is true, the parameters used are the soft Higgs masses at an input scale mx, $\{ m_{H_1,0}^2, m_{H_2,0}^2, m_{S_0}^2\} $, and the observables are $\{M_Z^2, \tan\beta, s\}$, irrespective of the value of softsusy::Z3. If softsusy::SoftHiggsOut is false and softsusy::Z3 is true, the parameters are taken to be $\{\lambda_0, \kappa_0, m_{S_0}^2\}$ at mx. The observables in this case are $\{M_Z^2, \tan\beta, \lambda\}$. If both flags are false, the parameters used are $\{\mu_0, m_{3_0}^2, \xi_{S_0}\}$ and the set of observables is $\{M_Z^2, \tan\beta, s\}$.

The top Yukawa $y_t$ can be included in the set of parameters, and $M_t^2$ in the set of observables, by calling setIncludeTopFlag() with the desired flag. Whether $M_Z^2$ and $M_t^2$ are taken to be the pole or running masses may be set by calling setUseRunningMassesFlag() with the appropriate flag. By default the pole masses are used.

The treatment of the soft SUSY breaking trilinears can be modified using the setUseSugraTrilinearsFlag routine. If set to true, the independent parameters are taken to be the capital $A$ trilinears, e.g. $A_\lambda = a_\lambda / \lambda$. In this case, it is the quantity $A$ that is held fixed in partial derivatives, rather than the quantity $a$. If this flag is false, the trilinears $a$ are treated as independent of the corresponding coupling, and are held fixed in the partial derivatives. By default this flag is false, i.e. the $a$ couplings are taken to be the independent parameters.

double softsusy::NmssmJacobian::calcDeltaJ ( const NmssmSoftsusy m)

Calculates the fine-tuning using the Jacobian measure.

Parameters
[in]mthe model to calculate the fine-tuning for
Returns
the value of the fine-tuning. It returns NaN if it had trouble calculating the fine-tuning

Calculates the fine-tuning for the model, using the Jacobian measure. The parameters are taken to be defined at the input scale mx obtained from a call to m.displayMxBC(), while the observables are calculated at the SUSY scale returned by m.calcMs(). The Jacobian matrix is calculated by calling calcFTInverseJacobian() internally, and can be accessed after the calculation.

Calculates the fine-tuning as in calcDeltaJ(const NmssmSoftsusy& m), but with mx set to the given value instead of that returned by m.displayMxBC().

Parameters
[in]mthe model to calculate the fine-tuning for
Returns
the value of the fine-tuning

Calculates the fine-tuning for the model, using the Jacobian measure. The Jacobian matrix is calculated using derivatives computed with respect to the logarithms of the parameters and observables. The parameters are taken to be defined at the input scale mx obtained from a call to m.displayMxBC(), while the observables are calculated at the SUSY scale returned by m.calcMs(). Internally, the Jacobian matrix is calculated by calling calcFTInverseJacobianLogs(), and can be accessed after the calculation.

Calculates the Jacobian transforming observables to parameters.

Parameters
[in]mthe model to calculate the Jacobian for
Returns
the value of the Jacobian

Calculates the Jacobian of the form $ J^{-1} = | \partial O / \partial p | $. The transformation is done in two stages. In the first, the observables at the SUSY scale, obtained from m.calcMs(), are traded for the parameters at this scale using the EWSB conditions. The Jacobian matrix for this transformation can be accessed afterwards using displayInverseEWSBJacobian(). Then, the parameters at this scale are transformed to parameters at the scale mx, obtained from calling m.displayMxBC(), using the RGEs. The Jacobian matrix for this transformation may be accessed by calling displayInverseRGFlowJacobian().

Returns

Calculates the Jacobian of the form $ J^{-1} = | \partial \ln O / \partial \ln p | $. The transformation is done in two stages. In the first, the observables at the SUSY scale, obtained from m.calcMs(), are traded for the parameters at this scale using the EWSB conditions.

Returns
the value of the Jacobian

Calculates the Jacobian of the form $ J = | \partial p / \partial O | $. The transformation, which is the inverse of that calculated by calcFTInverseJacobian(), is done in two stages. In the first, the parameters at the input scale mx, obtained from a call to m.displayMxBC(), are transformed to parameters $\{q\}$ at the SUSY scale, obtained from m.calcMs(), using the RGEs. The Jacobian matrix for this transformation may be accessed afterwards by calling displayRGFlowJacobian(). Then the parameters $\{q\}$ are traded for the observables at the same scale using the EWSB conditions. The Jacobian matrix for this second transformation can be accessed using displayEWSBJacobian().
