scenarios¶
This module contains all the NP hypothesis that we have considered and some auxiliar functions to implement them.
-
SMEFT19.scenarios.idemp(a, b)[source]¶ Creates an idempotent hermitic 3x3 matrix using to parameters.
- Arguments
a, b: Parameter of the matrix.
- Returns
A np.matrix.
-
SMEFT19.scenarios.massrotation(x)[source]¶ NP affects only the third generation in the interaction basis and then is rotated to the mass basis. Couplings to the first generation not negligible. C1 and C3 can be different.
- Arguments
x: Coordinates in the parameter space of the fit. x = [C1, C3, alpha_l, beta_l, alpha_q, beta_q].
- Returns
A dictionary containing the SMEFT Wilson Coefficients of the fit.
-
SMEFT19.scenarios.matrixwc(num, C, ll, lq)[source]¶ Returns the Wilson coefficients for Clq1 or Clq3 given the parameters of the idemp matrix.
-
SMEFT19.scenarios.rot2lqU1(x, M=1.5)[source]¶ Coupling of the U(1) leptoquarks obtained from the Wilson Coefficients.
- Arguments
x: Coordinates in the parameter space of the fit. It assumes scenario BI if len(x)==3 or scenario BII if len(x)==5.
[M: Mass of the leptoquark, in TeV. Default=1.5.]
- Returns
A np.matrix containing the couplings.
-
SMEFT19.scenarios.rotBI(x)[source]¶ Scenario BI: NP affects only the third generation in the interaction basis and then is rotated to the mass basis. Couplings to the first generation negligible.
- Arguments
x: Coordinates in the parameter space of the fit. x = [C, beta_l, beta_q].
- Returns
A dictionary containing the SMEFT Wilson Coefficients of the fit.
-
SMEFT19.scenarios.rotBII(x)[source]¶ Scenario BII: NP affects only the third generation in the interaction basis and then is rotated to the mass basis. Couplings to the first generation not negligible.
- Arguments
x: Coordinates in the parameter space of the fit. x = [C, alpha_l, beta_l, alpha_q, beta_q].
