17	17	Decays of the pseudoscalar resonances eta and eta' could turn out to be an important factor in fine-tuning the theoretical predictions for g_mu -2, one of the larger discrepancies between the Standard Model of Particle Physics and experimental measurements. In particular, eta' -> mu mu has not been observed yet, and doing so could represent a landmark achievement for the field, as well as the experiment that does it.

28	28	The decays of the pseudoscalar resonances eta and eta' may play a crucial role in refining theoretical predictions for g_mu - 2, which is one of the significant discrepancies between the Standard Model of Particle Physics and experimental measurements. Notably, the decay eta' -> mu mu has not yet been observed. Achieving this observation would be a landmark accomplishment for the field and the experiment that accomplishes it.

39	39	LLPs are an exciting avenue to discover new physics, but they are also known to be very challenging to detect, specifically in the context of hadronic colliders with large backgrounds. Detectors such as LHCb have been trying to find one of such particles, with no success so far.
