Most physical laws do not change if antiparticle, which has opposite charge, replaces particle {charge conjugation}|.
Universe particles can have handedness {chirality, universe}|. Zero-rest-mass particles conserve chiral symmetry. Neutrinos, pions, and kaons have handedness. Other particles conserve chiral symmetry. Particles with mass can change handedness by losing mass by symmetry transformations other than chirality.
Most physical laws do not change if coordinates invert through origin or reflect through plane {parity, physics}|, to change right-handed into left-handed, because most particles do not have handedness. Parity conserves in electromagnetic and strong nuclear forces but not in weak nuclear force, because neutrinos, pions, and kaons have odd intrinsic parity. Other particles, including all zero-rest-mass particles, have even intrinsic parity and no handedness. Parity violation is greater for charged particles, compared to uncharged ones.
Quanta {quantum number}|, such as electric charge, can be additive integers {additive quantum number}. Antiparticles have negative of additive-particle quanta. Mass is not additive. Quanta, such as parity and g-parity, can be multiplicative {multiplicative quantum number}, based on nth roots of unity. Fermions have -1 parity. Bosons have +1 parity. Two interacting fermions make boson: -1 * -1 = +1. Two interacting bosons make boson: +1 * +1 = +1. Three quarks make hadron, with parity -1: -1 * -1 * -1 = -1.
Perhaps, underlying field is particles {techniquark}, bound by force {technicolor}|.
