Discussion Overview

The discussion centers around the Bjorken scaling variables, specifically Y-bjorken and X-bjorken, in the context of deep inelastic scattering. Participants seek clarification on their definitions and differences, as well as related calculations.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant asks for an explanation of Y-bjorken and its difference from X-bjorken.
  • Another participant describes Bjorken X as a scaling variable used in deep inelastic scattering, noting its role in determining the momentum fraction of observed particles and its dependence on structure functions.
  • A different participant mentions Bjorken's discovery of light-cone scaling, also referred to as "Bjorken scaling," in the context of deep inelastic scattering involving hadrons.
  • One participant raises a question about calculating the scattering angle from the Bjorken Y variable, indicating a need for further exploration of this topic.

Areas of Agreement / Disagreement

Participants express varying levels of understanding and inquiry regarding the Bjorken variables, with no consensus reached on the specifics of Y-bjorken or its calculations.

Contextual Notes

The discussion includes references to specific calculations and definitions that may depend on additional context or assumptions not fully addressed in the thread.

Hi everybody,
this is my first post. So sorry for the possible trivial question.
Can someone explain me what is Y-bjorken?
And what is the difference with X-bjorken?

Thanks

Bjorken X is a scaling variable used in deep inelastic scattering..for more info on this experiment see this:

http://ikpe1101.ikp.kfa-juelich.de/briefbook_part_detectors/node42.html#41

It gives the momentum fraction carried by an inclusively observed particle. Structure functions are mainly dependent on this variable.

Bjorken discovered what is known as light-cone scaling, (or "Bjorken scaling") a phenomenon in the deep inelastic scattering of light on strongly interacting particles, known as hadrons (such as protons and neutrons)... think that's what you're looking for.
 


I have a question related to the Bjorken Y-variable which I don't believe has been covered by the link so far. How does one calculate the scattering angle $\theta$[\latex] from the Bjorken Y variable?
