The particle starts at the center of the channel, i.e., x = y = 0, with different values of the self-propelled angle θ. Trajectories have been produced by integrating equations for D 0 = D θ = 0, Ω = 0.3, and u 0 = 1. WebIOPscience A chiral phenomenon is one that is not identical to its mirror image (see the article on mathematical chirality). The spin of a particle may be used to define a handedness, or helicity, for that particle, which, in the case of a massless particle, is the same as chirality. A symmetry transformation between the two is called … See more The helicity of a particle is positive (“right-handed”) if the direction of its spin is the same as the direction of its motion.
