The Standard Model of elementary particle physics is almost consistent with experiments below O(100) GeV. However, there are still mysteries, for example,

"(a): What is an origin of mass generation?"

"(b): What is an origin of electroweak phase transition?" (which might be strongly related to an origin of Higgs field),

"(c): Why quarks and leptons have 3 copies (same quantum numbers but different masses)?"

(which is so-called mystery of generation, and we do not have any clues for it),

"(d): Why neutrino are much lighterthan other quarks and leptons?",

"(e): Why a charge of proton is thesame as minus charge of electron to an accuracy of 10²¹",

"(f): What is an origin of parity violation?",

"(g): Why our world id 4 dimension?", etc.

These mysteries implies an existence of fundamental physics behind the Standard Model (Beyond the Standard Model(BSM)), and they are important clues to search the BSM. I have researched the BSM by use of "supersymmetry (SUSY)", "extradimension theory", "grand unified theory (GUT)", "new building model". However, I also guess, the BSM is an as-yet-unknown theory, and the above mysteries are related among themselves through new physics beyond our imaginings. Keeping the possibilities, I intensively try to solve the mysteries with new and creative approaches. I also try to suggest new experiments to find out the BSM.
