What are the challenges in detecting the Higgs boson at CERN?

Click For Summary

Discussion Overview

The discussion revolves around the challenges in detecting the Higgs boson at CERN, touching on theoretical aspects of particle physics, the Standard Model, and the implications of the Higgs boson’s existence or non-existence. Participants also explore related educational resources and personal insights into their understanding of particle physics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant seeks beginner-level resources on particle physics to enhance their understanding of various particles and their interactions.
  • Several books are recommended for introductory and advanced studies in particle physics, including titles by Kane, Griffiths, and Halzen & Martin.
  • There is speculation about Stephen Hawking's stance on the Higgs boson, with some participants suggesting he has doubts about its discovery and may have made predictions regarding its existence.
  • One participant expresses uncertainty about whether the belief in the Higgs boson's non-existence is widely held among scientists or if it is a minority view.
  • Another participant suggests that while there is general agreement that something plays the role of the Higgs boson, the Standard Model may not fully encompass the complexities of particle physics.
  • A participant raises a question about the detection difficulties of the Higgs boson, noting that multiple bosons can occupy the same quantum state, unlike fermions, which cannot.
  • Concerns are expressed regarding the weak interactions of the Higgs boson, its unknown decay products, and the background noise from other particle decays complicating detection.
  • Clarification is sought on the distinction between "state" and "place" in the context of quantum mechanics.

Areas of Agreement / Disagreement

Participants express a mix of views regarding the existence of the Higgs boson, with some indicating a belief in its role within the Standard Model while acknowledging its limitations. The discussion remains unresolved on the broader implications of these beliefs and the challenges in detection.

Contextual Notes

Participants note limitations in their understanding and the complexity of the subject matter, indicating that further reading and exploration are necessary to grasp the nuances of particle physics and the Higgs boson.

Hi,

I'm sorry if this is in the wrong forum. I've been interested in science for while a white, most notably theoretical physics. In the end, I decided to go for a degree in Computer Science, but haven't lost my interest in physics.

With the introduction of CERN, I'd be interested if anyone could recommend some books (elementary), more specifically on particle physics.

I did physics up to A-Level standard (UK educational system). And have a good knowledge of the usual protons/neutrons/electrons, and a vague (very basic) understanding of muons, quarks, anti-protons,bosons.etc. but would like to get a better understanding of these various particles, and how they act, react, and interlink with the more commonly known particles.

I'm hoping this will give me a better grasp of the processes, and possibly math, behind CERN.

Could anyone recommend any (beginner,... based on the math/intellect here) books or websites that would provide a good basis for reading based on my level of knowledge?

I've read all the usual 'A Brief history of Time' and 'An Elegant Universe' type books, but I'm looking for a more scientific, explanation book.

I don't mean to be arrogant/up myself, but I was a straight A student, so I think if I can get to some good articles/books on my level of understanding, I might eventually be able to make sense of some of the equations in this forum!

On another note, I've heard some rumours that hawking has a bet that no Higgs Boson will be found with CERN, and that he had predicted the outcome (and expects a Noble prize if he is correct). Is this more media cr*p, of could anyone spread some light on it?

Thanks for reading this far!
 
Physics news on Phys.org
Hi jquail, and welcome to PF,

As introductory text to particle physics for the standard model, there are a couple of well-known ones
  • Gordon L. Kane, Modern Elementary Particle Physics
  • Griffiths D., Introduction to elementary particles
  • Perkins, Introduction to High energy physics
  • Halzen & Martin, Quarks & Leptons / Povh & Al, Particles and Nuclei: An Introduction to the Physical Concepts
More advanced if the others are too low level for you
  • Aitchison & Hey, Gauge theories in particle physics
  • Cheng & Li, Gauge theory of elementary particle physics
  • Donoghue & Al, Dynamics of the Standard Model (phenomenology)
  • Pokorski, Gauge field theories (theory)

Hawking is serious about the Higgs. He is not the only one with strong doubts. :rolleyes:
 
Thanks for the texts humanino. I will definitely check those out. I appreciate the time taken to recommend them. I just seem to find a lot of theories which i have thought myself at one point and have been discarded due to science beyond my current knowledge. I'd like to move up in the science ladder for lack of a better euphamism.

On another note I noticed the reply to my question "On another note, I've heard some rumours that hawking has a bet that no Higgs Boson will be found with CERN, and that he had predicted the outcome (and expects a Noble prize if he is correct). Is this more media cr*p, of could anyone spread some light on it?"

Is lack of the Higgs Boson a more common scientific belief? Or is hawking in the minority with regards to this belief?

Also, has anyone heard the Noble Prize quote from Hawking? I've only heard it through traditional media as opposed to Scientific Journals, so I'm not sure of its validity.
 
PS - Thank you for the welcome!
 
I just noticed that I wrote several times "& Al". I did not mean my neighbour Al, I meant "and others" as in "& al" but for some reason, I used a capital "A". That's silly.

I think everybody agrees that there is something playing the role of the standard model Higgs boson. But I would also imagine that the majority thinks the standard model single Higgs boson is not the end of the story. The standard model itself, as successful as it is, has shortcomings. I would elaborate on that, but others on this forum will be more qualified than me to do so.
 
I appreciate the insight. As much as I would love the others to give me insight on this, I doubt my knowledge of physics would allow me to comprehend it at this point.

But hey, it's worth a try! ;)
 
To give an indicator of my level of understanding, it lies around the level of the wiki article - http://en.wikipedia.org/wiki/Identical_particles . I'm not sure, but this seems like a good knowledge base to build from (not from my knowledge, but from were you can see my knowledge is at, and to advise, if possible, any relevant materials (other than wikipedia hopefully!)).

I would appreciate any books/articles than would give me a better understanding than in the previous wikipedia article.

I thought you meant Al Gore. :smile:
 
Based on my early reading in http://en.wikipedia.org/wiki/Identical_particles,
is it harder to detect a Higgs boson, because several bosons can occupy the same quantum state, versus an electron, for example, as only one can occupy one quantum state at one time (a fermion?)?

However, from what I know, electrons don't actually definitively occupy a particular space at a particular time (fermions?), but have a possibility of occupying that space, without and definitive possibility. So is a quantum space for bosons the same as that for fermions?

I think what I'm trying to say (assuming quantum space is the same space that I am talking about in the previous text) , what is the difference between no possibility of occupying the same quantum space of borons vs. the possibility of occupying the same actual space of fermions.

I'm not too sure if I'm making sense with this, but I would apprecaite your opinions, or books, that would give me some guidance towards this.

Thanks again!

No its hard to detect the higgs boson since
1) interact weakly
2) unknown decay products, mass is not specified in theory
3) lots of background from other particle decays.

And "state" and "place" is not the same thing.
