Checking the particles and parameters within Mathematica

General information about particles

To get an overview of all particles of the different eigenstates, one can use

Particles[Eigenstates]

e.g. Particles[GaugeES] or Particles[EWSB] for the gauge eigenstates or the eigenstates after electroweak symmetry breaking (EWSB), respectively. Instead of specifying the eigenstates, one can also use

  1. Particles[Current]: prints the particles for the currently considered eigenstates (usually the last entry of NameOfStates)
  2. Particles[ALL]: lists all particles ever present in the model

The output is a list with the following information about each particle:

  1. Name of the particle
  2. Number of first generation (can be different from 1 in effective theories)
  3. Number of last generation
  4. Indices of the particle: the name of the index and the length of it is given

Examples

  1. left-handed leptons {FEL, 1, 3, F, {{generation, 3}}}

  2. right-handed up-quarks {FUR, 1, 3, F, {{generation, 3}, {color, 3}}}

  3. Photon {VP, 1, 1, V, {{lorentz, 4}}}

  4. Gluon {VG, 1, 1, V, {{color, 8}, {lorentz, 4}}}

  5. Up-Squarks {Su, 1, 6, S, {{generation, 6}, {color, 3}}}

  6. Z-Ghost {gZ, 1, 1, G, {}}

General information about parameters

All parameters in the considered model are saved in

parameters

This shows for each paramter the following information:

  1. Name of the parameter
  2. Name of possible indices (usually generation indices)
  3. Name of the dimension of all indices

Examples

  1. Hypercharge coupling {g1, {}, {}}

  2. Up Yukawa coupling {Yu, {generation, generation}, {3, 3}}

  3. Up-Squark mixing matrix {ZU, {generation, generation}, {6, 6}}

Special lists

There are some lists which contain the names of parameters or particles which specific properties:

Real parameters and fields

All parameters and particles which are real (i.e. conj[x]=[x]) are saved in

realVar

Majorana particles

All Majorana particles are saved in

MajoranaPart

Massless states

All massless particles for a given set of eigenstates are saved in

Massless[Eigenstates]

Masses in general

SARAH automatically calculates the tree level masses of all particles. This information is saved in

Masses[$EIGENSTATES]

It returns are a list with replacements rules. First, a statement Mass[] with the name of the particle is given followed by the value. There are three possibilities for the value

  1. Expression: if an expression is used for a mass, SARAH has calculated the tree level mass depending on other parameters of the model.
  2. MassGiven: this means that a numerical value for the mass was given in the particle file
  3. MassRead: this means that the value of the mass was read in from a LesHouches input file.
