The collisions happen at the subatomic level in a highly controlled environment. Even though the particles collide at high energy, they have a very tiny mass. so the amount of energy involved is not enough to cause macroscopic harm. Also, particles formed after the collision are highly unstable. And even if things like microscopic blackholes are produced, they would evaporate instantly.
@ChiralAnomaly As you pointed, lepton flavor violation has been observed in neutrino oscillations. But that is only in the case of the neutral sector. But still, there is no hint of lepton flavor violation in the charged sector. Only experimental limits are being put on such lepton flavor violating processes in the charged sector. But in the current scenarios, the above decay should be violated in the Standard Model. Maybe with the inclusion of new physics the process may happen.
Hi, I copied the CKMFitter plot from the ckmfitter.in2p3.fr/www/results/plots_summer19/… site. Which is managing such plots over the years. Any experts here on these CKM fitter plots can recognize/identify my doubts easily I hope.
This is a well-known method for estimating parameters in the data analysis. If you follow any standard book on statistical method for data analysis in particle physics, more details can be found. Here I can only say the likelihood function will carry an extra PDF for total number of events in the case of extended maximum likelihood as compare to maximum likelihood function. Upon maximizing the likelihood function one can get the parameter of interest.
Hi, Thank You for your reply! Just a general query, How $N_{i}^{(theo)}=N_{i}^{(obs)}/\epsilon_i$? And $N_{BB}$ in the formula; is the number from theoretical prediction?
