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_i...-"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." -
A similar approach: more forceful Higgs early on:-

In the "primordial soup" that existed after the Big Bang, there were almost equal amounts of particles of antiparticles, except for a tiny asymmetry: one particle per 10 billion. As the universe cooled, the particles and antiparticles annihilated each other in equal numbers, and only a tiny number of particles remained; this tiny amount is all the stars and planets, and gas in today's universe, said Kusenko, who is also a senior scientist with the Kavli Institute for the Physics and Mathematics of the Universe.-"The research also is highlighted by Physical Review Letters in a commentary in the current issue.-"The 2012 discovery of the Higgs boson particle was hailed as one of the great scientific accomplishments of recent decades. The Higgs boson was first postulated some 50 years ago as a crucial element of the modern theory of the forces of nature, and is, physicists say, what gives everything in the universe mass. Physicists at the LHC measured the particle's mass and found its value to be peculiar; it is consistent with the possibility that the Higgs field in the first moments of the Big Bang was much larger than its "equilibrium value" observed today.-"The Higgs field "had to descend to the equilibrium, in a process of 'Higgs relaxation,'" said Kusenko, the lead author of the UCLA research."

The Higgs has given off top quarks and an anti-top quark, heavy particles:

"Today physicists reported an important observation that could help us understand this fascinating particle and clarify the origins of the mass. Using the Large Hadron Collider (LHC), the world’s most powerful particle accelerator, located at the CERN laboratory on the French–Swiss border, scientists observed collisions that produced not only Higgs bosons, but also a top quark and its antimatter counterpart, an anti–top quark.

"These quarks are the heaviest known fundamental particles and had never before been seen along with Higgs bosons as the products of a collision. I am a scientist on one of the teams behind the announcement and we are all very excited. Until these measurements we had only indirect evidence of how top quarks and Higgs bosons interact. Now we can see these dealings up close.

"The reason for this is subtle. The Higgs boson’s own mass comes from two sources: one part arises directly from its interactions with the Higgs field, but there is another indirect contribution. Like all subatomic particles, the Higgs boson can briefly transform into other particles—for instance, top quarks, W and Z bosons, and even pairs of Higgs bosons. While in this fluctuated state these transformed particles can also interact with the Higgs field and indirectly contribute to the Higgs boson’s mass.

"This contribution to the Higgs mass is expected to be enormous, unless the effects of the top quark and the W, Z and Higgs bosons can cancel out this mass very precisely. For now that seems unlikely (and certainly unexplained), so this presents a serious mystery. Thus, it is important to understand the interaction between Higgs bosons and top quarks to try to shed some light on this pressing conundrum.

"Aside from the unanswered questions regarding the mass of the Higgs boson itself, there is another reason to be interested in the relationship between the top quark and the Higgs boson. The top quark is the particle that interacts most with the Higgs field—we know this because it is the heaviest known particle, and particles gain mass according to how strongly they deal with the field.

"The intimate relationship between the top quark and the Higgs may offer us a favored route for discovering new particles in nature. Because of the mystery remaining around how the Higgs generates mass, it is entirely likely that undiscovered particles will first appear in collisions in which the Higgs field plays a prominent role. Thus, events in which the top quark and Higgs boson simultaneously appear are an attractive laboratory to investigate new physics."

Comment: Even though a bigger LHC is needed for higher energy particles, discoveries within the standard model, discoveries continue.
