New results indicate that new particle is a Higgs boson

Click For Summary
SUMMARY

The ATLAS and CMS collaborations at the Large Hadron Collider (LHC) have presented new preliminary results confirming that the particle discovered last year is increasingly resembling a Higgs boson. This finding is based on an analysis of two and a half times more data than was available during the initial discovery announcement in July. While the particle appears to be linked to the mechanism that imparts mass to elementary particles, it remains uncertain whether it is the Standard Model Higgs boson or a lighter variant predicted by theories beyond the Standard Model. The Higgs boson is confirmed to describe inertia for elementary particles, but it does not account for gravity.

PREREQUISITES
  • Understanding of the Standard Model of particle physics
  • Familiarity with the Higgs mechanism and its implications
  • Knowledge of particle detectors like ATLAS and CMS
  • Basic concepts of quantum field theory
NEXT STEPS
  • Research the latest findings from the Moriond Conference presentations
  • Explore the implications of the Higgs boson on mass and inertia
  • Investigate theories beyond the Standard Model of particle physics
  • Learn about the role of dark matter in the universe
USEFUL FOR

Physicists, researchers in particle physics, and students interested in the latest developments regarding the Higgs boson and its implications for mass and fundamental forces.

This was released today so I'm not sure if most have seen it yet. It appears that "a" Higgs Boson is confirmed.

At the Moriond Conference today, the ATLAS and CMS collaborations at the Large Hadron Collider (LHC) presented preliminary new results that further elucidate the particle discovered last year. Having analysed two and a half times more data than was available for the discovery announcement in July, they find that the new particle is looking more and more like a Higgs Boson, the particle linked to the mechanism that gives mass to elementary particles. It remains an open question, however, whether this is the Higgs boson of the Standard Model of particle physics, or possibly the lightest of several bosons predicted in some theories that go beyond the Standard Model. Finding the answer to this question will take time.

To me, these detectors are works of art. Yea Standard Model.

Well, don't get too excited. Remember, the bigger they come, the harder they fall...

That's mass for ya.

I used to get a bit concerned several years ago when people referred to CMS as "See-A-Mess".

So great, how it's all turned out.
 
Not sure whether it is good news or bad news...

Question from a non-physicist:

Does the Higgs boson explain both aspects of mass, inertia and gravity, or only inertia?

Gravity is not part of the standard model of particle physics, hence the Higgs is unrelated to gravity in this model(*). The Higgs boson describes inertia for elementary particles. Please note that most of the mass of ordinary everyday objects is not due to the Higgs (rather, it is "frozen energy" in the glue field of hadrons). Even worse, please remember that most of the mass in the universe is not "ordinary" (dark matter).

edit
(*) you can in principle describe gravity with the same formalism as the standard model of particle physics, namely perturbative quantum field theory. However, this description fails at high energies (very high energies), so gravity is not part of the "standard" version.

For future visitors : this thread used to be in the "general discussion", hence the above informal tone...

No idea. I just saw this linked on facebook and decided to post it here.

The papers presented at Moriond, especially the Thursday morning session.
