Jun 6, 2015 at 22:01 | comment | added | CuriousOne | The one way we can change the coupling is by changing the particle type for the collision (aka "new accelerator"). Once that's fixed and the beams are colliding head on (I have not seen a large angle collider design, but it might be an interesting question if that would make sense), then the remaining choice is polarizations. I don't know if that changes branching ratios or only the angular distribution of the detected decay particles. The ratios are basically the relative probabilities for decay channels and they are, if I get this right, much better known than the absolute probabilities. | |

Again, questions before reading up more is not a good idea. I would need to read up more on it, no doubt about that. What's a branching ratio, guessing it's the proportion you get out of each possible channel? | |
Jun 6, 2015 at 21:46 | comment | added | CuriousOne | The branching ratios are given by the couplings, so there is nothing to tune. The total "production cross section", which is the most important parameter for an experiment, that changes with beam energy and it can be resonant, but for the Higgs in the LHC it's not: image.slidesharecdn.com/elwmskcc20120420-140207110356-phpapp01/…. If we could control all the kinematic parameters in a collision, the Higgs should be easy to detect, I believe, but then we can't! | |
