Couplings of sfermions to h Higgs boson

Click For Summary
SUMMARY

The discussion focuses on the detailed calculations of sfermion couplings to the lightest h Higgs boson within the Minimal Supersymmetric Standard Model (MSSM). The reference to reach is Equation (1.109) from the paper [arXiv:hep-ph/0503173]. Key resources mentioned include the foundational work by H.E. Haber and G.L. Kane in Phys. Rep. 117,75 (1985) and Atchinson's book "Supersymmetry in Particle Physics" (2007), which covers the derivation of relevant matrix equations from F-terms, D-terms, and soft supersymmetry-breaking terms.

PREREQUISITES
  • Understanding of Minimal Supersymmetric Standard Model (MSSM)
  • Familiarity with Lagrangian mechanics in particle physics
  • Knowledge of F-terms and D-terms in supersymmetry
  • Access to arXiv:hep-ph/0503173 for specific equations
NEXT STEPS
  • Study the derivation of Equation (1.103) in [arXiv:hep-ph/0503173]
  • Review H.E. Haber and G.L. Kane's Phys. Rep. 117,75 (1985) for foundational concepts
  • Examine Atchinson's "Supersymmetry in Particle Physics" (2007) for detailed calculations
  • Explore the implications of soft supersymmetry-breaking terms in MSSM
USEFUL FOR

Researchers and students in theoretical physics, particularly those focusing on supersymmetry and Higgs boson interactions, will benefit from this discussion.

Hi all,

I try to find the detailed calculations of the couplings of sfermions to the lightest h Higgs boson
in MSSM, I want to reach Equ. (1.109) in [arXiv:hep-ph/0503173],

Do you know any useful reference ?

Bests,
S.S.

What do you mean by detailed calculations? The coupling constant is in the lagrangian as the factor multiplying the fields' couplings. Or in your ref, the couplings are given by the 1.103 equation...
However you could take a look at:
H.E. Haber and G.L. Kane
Phys. Rep. 117,75 (1985)
I think...
 
Well, I meant to derive a matrix 1.104 in my Ref., which comes from F-terms, D-terms and soft SuSy-breaking terms as it explained, I found these calculations in Atchinson's book : Supersymmetry in Particle Physics (2007) .

S.S.
