mass hierarchy problem
 
what is mass hierarchy problem.i have some idea of solving this ,i can do lot of mathematics but i want to understand fine tuning,and i want why supersymmetry is prefered to solve mass hierarchy problem

The mass hierarchy problem asks one simple question: Why are the masses of ordinary particles almost negligible compared to the Planck mass? I don't know the answer

... Why are the masses of ordinary particles almost negligible compared to the Planck mass? ...

Frank Wilczek had a series of 3 articles in "Physics Today" around 2001
that dealt with that
(only in a speculative way
because it is an unsolved problem
but as he is a majorleague theorist with very broad clear vision
it can still be enlightening to read his opinions
you can learn something although the answer is not known)

I think you can find it by googling Wilczek and the title
"Scaling Mount Planck"

---------------------------

Shakeel, maybe you can tell me something about the mass h. problem.
You may already have made some progress.
Wilczek poses the question of why the planck mass is a big number (13 quintillion, 13 x 1018) times the proton mass

or why the proton mass is so small in natural units---- 1/(13 quintillion) of the planck mass.

and he tries to conjecture some explanation for this, but I think without
presuming supersymmetry

do you have some idea of how people now explain this?
