Is there an Anti-Higgs Boson

The maximal amount of energy that can get released is the full energy of the particles. At the LHC, this is large in terms of particle physics, but still tiny for our macroscopic world: the total energy of a proton-proton collision is about 0.000001 J. And 1 J (a million times more) is just enough energy to lift an apple up by 1 meter.

In addition, even single Higgs bosons are rare - the "collision" (better: interaction) of two Higgs bosons is extremely rare. And they do not annihilate in the way regular matter plus antimatter would do, they form other particles.

Found it (including the following posts), the number 1 was for the whole observable universe.

 

I'm quite sure he did not say that. And if he did, it was wrong.
You can get conditions close to those we had shortly after the big bang, but that is a completely different statement.

 

That depends on the collision. Examples:

• Low-energetic positrons, annihilating with electrons, produce a pair of photons (gamma rays). This is used in PET scans, where it happens inside the human body. Certainly not a second big bang!
• High-energetic positrons and electrons can produce new particles, including protons, more electrons and various other particles and antiparticles. The antiparticles can react with particles afterwards and annihilate again. Energy is conserved, so whatever happens, the total released energy is just the initial energy of the collision partners (which is tiny in our macroscopic world).
• If you collide heavy ions with heavy ions at high energy, you get a very small, very hot collision region for a very short time. This region has conditions similar to those we had shortly after the big bang, and it allows us to study them today. The collision produces thousands of new particles that fly towards the detectors. Again, the total energy is given by the initial energy of the ions, and tiny (about 0.0001 J at the LHC).
• Hypothetical: If you have some larger clump of antimatter, it would make a good bomb. Releasing this antimatter leads to a reaction with matter, converting all the antimatter and an equivalent amount of matter to radiation and heat. This conversion releases a huge amount of energy - even 1 gram of antimatter would give an explosion similar to the Hiroshima bomb.

There is no large clump of antimatter. If you would have all the antimatter that has been produced in labs in the last decades at once, it would just be enough to make hot coffee.
