A changing Higgs in the early universe might have set up the imbalance of much more matter than antimatter:-http://www.scientificamerican.com/article/higgs-boson-could-explain-antimatter/?WT.mc_id=SA_DD_20150220-"The Higgs field is thought to pervade all of space and imbue particles that pass through it with mass, akin to the way liquid dye gives Easter eggs color when they are dunked in. If the Higgs field started off with a very high value in the early universe and decreased to its current lower value over time, it might have briefly differentiated the masses of particles from their antiparticles along the way—an anomaly, because antimatter today is characterized by having the same mass but opposite charge as its matter counterpart. This difference in mass, in turn, could have made matter particles more likely to form than antimatter in the cosmos' early days, producing the excess of matter we see today. “It is a nice idea that deserves further study,” says physicist Kari Enqvist of the University of Helsinki, who was not involved in the new study but who has also researched the possibility that the Higgs field lowered over time. “There is a very high probability for the Higgs field to have a high initial value after inflation.”"
