Big bang on toast? I’ve got 5 dimensions on a pancake.
This morning I had a chuckle at a piece of satirical news,”Athiest Sees Image of Big Bang in Piece of Toast.” However, armed with leftover frosting from my Gingerbread-[Feyn]men, I decided that I could go one step further. Ladies and gentlement, I present to you five-dimensional Higgsless electroweak symmetry breaking… on a pancake!
I tried to include a reference, but unfortunately it was the wrong reference. I meant to say hep-ph/0308038. (Also, I may have my gauge groups a bit off… I think I meant on the UV brane and on the IR brane.) The idea is to use a warped extra dimension, rather than the Higgs mechanism, to induce electroweak symmetry breaking. The image was inspired by C. Grojean’s talk at the 2008 Higgs-Maxwell meeting yesterday.
I had leftover batter, so I decided to continue with the EWSB theme and sketch a plot of the dominant Higgs decays as a function of Standard Model Higgs mass:
The pancake is a bit burnt along the X-axis, but what’s plotted is the Higgs mass. The mode is a bit harder to tag than the mode, with a transition at Gev. Thus a heavier Higgs will be easier to discover at the LHC. The other modes plotted (not to scale!) are (green), (yellow), and (red).
Shrove Tuesday, a.k.a. Pancake Day (in the UK) was last week. I had been planning to try out a new crepe recipe then, but was delayed until today. Why don’t we celebrate Pancake Day in the US? I guess we have pancakes often enough?
Anyway, this opens the door to all sorts of physics/pancake jokes. I’ll just offer this funny paper title: arXiv:astro-ph/0509039, “Local Pancake Defeats Axis of Evil.”
