In the November 2017 Sci-Am article "Chasing Beauty" (about LHC), it says: "The rules of quantum mechanics tell us that what happens in nature is driven by the net contribution of all the valid diagrams we can draw, although the simplest and most obvious have the greatest weight. Hence, all these possible decay paths should play a role, and we must account for them in the calculations we make predicting the rate of the decay, the trajectories of the products and other particulars. In other words, even when a particle decays in a normal process involving only conventional members of the Standard Model, it feels the effects of every possible particle out there. Therefore, if a measurement of a decay disagrees with our calculations based only on the Standard Model ingredients, we know that something else must be at work. This fact is the guiding principle behind LHCb’s strategy of indirect searches for new particles and new physics. Because these new particles would be virtual participants in every decay that we measure, the mass of the particles we can detect is not limited by the energy capacity of our accelerator. In principle, if we studied the right decay processes with enough precision, we could observe the effects of particles even heavier than those that can be created and detected within ATLAS and CMS." 1. Questions.. for decay scenarios like the following: Does the presence of supersymmetric particles for example affect it too? Or do you have to do specific experiments to measure other contributions? 2. What decay scenario experiments where you can detect the presence of all known particles in the universe? 3. Can all the particles and even possible dark matter forces also affect the decays in any decay experiments? 4. If yes.. are there nothing that won't affect the decays? 5. If yes, that means we already have constrains of all new particles that can exist? 6. What if there were unique non-gauge non-SM fields that won't change the decays.. is this possible? Thanks.
