Bogdan Dobrescu, Adam Martin and Patrick J Fox from Fermilab say this large asymmetry effect can be accounted for by the existence of multiple Higgs bosons.
They say the data points to five Higgs bosons with similar masses but different electric charges.
Three would have a neutral charge and one each would have a negative and positive electric charge. This is known as the two-Higgs doublet model.
And:
The Standard Model only has one Higgs "doublet". Although we tend to think of the Higgs boson as one particle, it actually comes in a package of four, explained Dr Martin.
"In the Standard Model, you only see one of them because the other three are absorbed into [other parts of the scheme] such as the W and the Z bosons. There's only one left," he told BBC News.
"So if you want to add another Higgs doublet - you actually have to add four more particles."
