Quarks are the smallest known constituents of matter and cannot be further divided. They combine in groups to form hadrons, such as protons and neutrons. Electrons are also fundamental particles, but they belong to the lepton family, not quarks.

The Higgs boson, discovered at the Large Hadron Collider (LHC), is associated with the Higgs field and gives mass to other particles through the Brout-Englert-Higgs mechanism. It is a fundamental particle in the Standard Model of particle physics.

In the Standard Model of particle physics, there are six types, or "flavors," of quarks. These quark flavors are up, down, charm, strange, top, and bottom.

The electromagnetic force, mediated by photons, governs interactions between charged particles. It is responsible for phenomena such as electromagnetic attraction and repulsion, making it crucial for understanding atomic and molecular behavior.

Annihilation is the process in which a particle and its corresponding antiparticle collide and mutually annihilate, converting their mass into energy in the form of photons (usually gamma rays). This process obeys conservation laws, including conservation of charge and energy.

Neutrino oscillation is a phenomenon where neutrinos of different flavors (electron, muon, tau) change into each other. This phenomenon requires at least three distinct neutrino flavors, as they mix and change during propagation.

Neutrinos are associated with the conservation of the "lepton number" in particle interactions. The lepton number is conserved in various particle reactions, and neutrinos are essential for maintaining this conservation law.

The lifetime of a free neutron when it is not bound within an atomic nucleus is approximately 1.6 microseconds. Neutrons outside a nucleus decay into a proton, an electron, and an antineutrino through the weak nuclear force.

Flavor is a property of particles that distinguishes different types within a particle family. Changing a particle's flavor means transforming it into a different particle within the same family while preserving other characteristics like mass.

Quintessence is a hypothetical form of dark energy, a fundamental force responsible for the accelerated expansion of the universe. Unlike dark matter, which exerts gravitational attraction, quintessence is associated with repulsive effects and plays a role in the cosmic acceleration.
