Note that it is not "me who is trying", but more the work of an entire community :)
I was referring to a group of scientists (maybe not the entire community, but definitely a dozen at least) :)
So the nature of the particles that you are colliding, their speed, and trajectories, doesn't vary based on what the community want to try ? They "just" need more data to see something that has less probability than the other events ?
Only the nature and their energy (that's better than speed) of the particles define the machine.
The rest (signals and trajectories) is dictated by quantum field theories. Which quantum field theory to choose tells you which signal to expect. You take the Standard Model as your background, and then your favourite theory as a signal. Then, we do the computations and design strategies about how to filter all collisions to make sure that the selection focuses on the signatures of the considered "signal theory" by keeping the "Standard Model background" small.
Is it clearer?
Yes, it's very clear! Thank you for your answers :)
You are very welcome.
Thanks also for your comment and your question. This is always appreciated!
