Help with Higgs Strahlung Production & Formulating a Matrix Element

In summary, the conversation discusses two questions related to Higgs strahlung production and the formulation of an equation for the amplitude of a 4th order correction. The first question asks about the number of possible Feynman diagrams for this production, with the mediator being a Z-particle. The second question specifically asks for an equation for the amplitude of one of these diagrams. The person asking for help clarifies that they are only interested in the weak corrections of 4th order and that they have already written an equation, but are unsure if it is correct due to the challenge of treating the H ray. Finally, they inquire if anyone knows the number of possible diagrams for this specific case.

Hello dear everyone

I would like to ask if someone can help me with the following two things:

1) How many different feynman diagrams can one possibly draw for Higgs strahlung production that is of 4th order? The mediator should be Z-particle.

2) Formulate an equation for the amplitude (also known as the matrix element) of just one of those diagrams.

Your help is so much appreciated.

Do you mean a 4th order QCD correction? Or you want the weak corrections and qcd corrections?

Can you write a 1st order correction matrix element?
 
  • #3
It should only be the weak corrections of 4th order, be cause we are using electron and positron.

I have written one, but not sure if its correct.. What is challenging is the H ray; how to treat that?

Do u know how many different diagrams one can make of 4th order correction in this case? :)

1. What is the Higgs Strahlung production process?

The Higgs Strahlung production process refers to the production of a Higgs boson in association with a Z boson. It is one of the main production mechanisms for Higgs bosons at the Large Hadron Collider (LHC).

2. How is the Higgs Strahlung production process relevant to the Standard Model?

The Higgs Strahlung production process is relevant to the Standard Model because it is a predicted mechanism for the production of Higgs bosons in the Standard Model. It also plays a crucial role in the study and confirmation of the Higgs boson and its properties.

3. What is a matrix element in the context of Higgs Strahlung production?

In particle physics, a matrix element is a mathematical expression that represents the amplitude of a particle interaction or decay. In the context of Higgs Strahlung production, the matrix element is used to calculate the probability of producing a Higgs boson in association with a Z boson.

4. How do scientists formulate a matrix element for Higgs Strahlung production?

Formulating a matrix element for Higgs Strahlung production involves using the principles of quantum field theory and the Standard Model to calculate the amplitude of the Higgs Strahlung process. This involves taking into account the properties of the particles involved, such as their masses and couplings, and using Feynman diagrams to represent the interactions.

5. Why is understanding Higgs Strahlung production important for scientific research?

Understanding Higgs Strahlung production is important for scientific research because it allows us to study and confirm the properties of the Higgs boson, which is a crucial piece of the Standard Model. It also helps us to explore and understand the fundamental forces and particles that make up our universe.
