About Me
I am a third year PhD student (my how time has flown...) working within the ATLAS Collaboration, which is one of the multi-purpose detectors installed at the Large Hadron Collider in CERN. I have completed a period of 18 monthes living and working out at CERN on a long-term attachement from my home institution (Royal Holloway, Univeristy of London). This tumblr is a platform from which I can try to educate and inform others interested in particle physics and wonderful science, as well as provide some insight into the workings of a PhD.

Open publication -

I’m currently attending a summer school at Fermilab (which is awesome, I know) and means I am getting to experience American culture for the first time.

I can only assume self-reblogging is frowned upon, but I came upon an article I wrote explaining some of the mathematics behind the Higgs mechanism a couple of years ago. After attending some lectures on spontaneous symmetry breaking (and general Standard Model theory) I think the explanation still holds true, so good going past-me :)

Thought I’d share it anyway. I’ll post some pictures of Fermilab (FNAL) some point soon too :)

Spontaneous Symmetry Breaking and the Higgs Mechanism - Some Notes

One of the things I have always found interesting in Particle Physics is Spontaneous Symmetry Breaking. When I was in Sixth Form, it was articles on the unification which I enjoyed reading the most. 

As I have done a couple of courses now on the Standard Model and the unification within it, I thought I would try my hand at writing up some notes which try to explain the methodology behind the Higgs mechanism, because in truth, it is not too difficult.

There are some parts that people may not be able to fully comprehend as I have probably assumed to much knowledge of quantum field theory nomenclature.

  • If you are vaguely aware of index notation, it should be straight forward to follow. 
  • If you understand differentiation, and not index notation, it should still be accessible.
  • If you want an overview of the maths behind the Higgs mechanism, instead of just reading Higgs boson everywhere and not understanding why there is even a boson, please have a read.

I have tried to explain things clearly as I have gone along. 

As always, if you have questions about this, please ask, as I would be more than willing to expand on some points if people want to learn more.

Voyager 1 is still sending data back, very slowly. Your cellphone sends and receives data at least 1000x faster.

Fun fact: The reason why the Deep Space Network antennae are in Madrid, Goldstone, and Canberra is so that they can always be in touch with distant craft like Voyager 1, no matter which side of Earth is facing the spacecraft.
