tweedle

v. fiddle, fuss with; twist, coil; chirp, produce high-pitched sounds; play lightly on a musical instrument; attract with music, lure with music

In particle physics, preons are postulated "point-like" particles, conceived to be subcomponents of quarks and leptons. The word was coined by Jogesh Pati and Abdus Salam in 1974. Interest in preon models peaked in the 1980s but has slowed as some proposed models were ruled out by collider experiments and no model was able to predict a new experimental result. Additionally, after the first superstring revolution, many particle physicists became convinced that string theory offers the most logical research program to pursue, in understanding the nature of elementary particles. It was thought string theory was more promising than preon theory, and many particle physicists committed their research efforts in this direction. More recently confidence in string theory has waned in some quarters, leading to renewed interest in alternative approaches, including preon models.
