| | 23 | '''Description of the model''' |
| | 24 | |
| | 25 | This model is an extension of the SM by introducing a linearized singlet dilaton field ''S'' and a vector-like top partner ''T'' with the same quantum number as the right-handed top quark. The low energy effective Lagrangian of the MDM is given by [1] [2] [3]: |
| | 26 | |
| | 27 | |
| | 28 | where ''L'',,SM,, is the part of the SM Lagrangian without the Higgs potential, ''M'' presents the scale of a certain strong dynamics in which the fields ''T'' and ''S'' are involved, ''q,,3L,,'' is the ''SU(2),,L,,'' left-handed quark doublet of the third generation, and ''M,,H,,'', ''M,,S,,'', ''λ,,S,,'', ''κ'' and ''λ,,H,,'' are all free parameters describing the new Higgs potential. |

| | 30 | '''Model files''' |
| | 31 | * MDM.fr: the main model file. |
| | 32 | * MDM.nb: the example of Mathematica notebook that loads the model, calculates the Feynman rules and extracts the model files within the CalcHEP output and the UFO output. |
| | 33 | * Minimal-Dilaton-Model-CH.tar.gz: the model files within the CalcHEP output. |
| | 34 | * Minimal_Dilaton_Model_UFO.tar.gz: the model files within the UFO output. |
| | 35 | |
| | 36 | Notes: |
| | 37 | |
| | 38 | * Except the free parameters in the SM, there are still five free parameters in the MDM： |
| | 39 | * ''f'': the vacuum expectation value of Dilaton; |
| | 40 | * ''θ,,L,,'': the mixing angle of top and top partner; |
| | 41 | * ''θ,,S,,'': the mixing angle of Higgs and Dilaton; |
| | 42 | * ''m,,s,,'': the mass of dilaton-boson; |
| | 43 | * ''m,,t^'^,,'': the mass of top partner. |
| | 44 | * The dilaton-boson mass and width are set using the parameters MsDM and WsDM, respectively. |
| | 45 | * The top partner mass and width are set using the parameters MTP and WTP, respectively. |
| | 46 | * The vacuum expectation value of Dilaton is given by vevf. |
| | 47 | * The tangent value of Higgs-Dilaton mixing angle is set by ts. |
| | 48 | * The sine value of top and top partner mixing angle is set by sl. |
