Subject: Can Charge change as a particle is accelerated?

This is in responswe to question 960898806.ph.  Since most[if not all] of 
the empirical data on particles approaching the speed of light has been 
done on charged particles in particle accelerators, why can the data not 
be as accurately explained by a decrease in charge at constant mass as by 
an increrase in mass at constant charge.
