NOUN
- a theory of strong interactions between elementary particles (including the interaction that binds protons and neutrons in the nucleus); it assumes that strongly interacting particles (hadrons) are made of quarks and that gluons bind the quarks together
How To Use QCD In A Sentence
- The interest in collisions of high-energy nuclei as a possible route to a new state of nuclear matter began with the emergence of QCD in the late 1970s.
- BRAHMS was designed to measure the momentum of scattered hadrons, part of the study of quantum chromodynamics (QCD), investigating the strong force that holds atomic nuclei together. Siehe, ein Ackermann wartet auf die köstliche Frucht der Erde
- But still we do need a cutoff (to be differentiated from the scale at which the theory is defined) to handle UV divergences, for example in perturbative QCD. Richard Feynman Needs His Orange Juice
- QCD tells you explicitly how to evolve these non perturbative functions, but that has to be done with an approximation. How low is low? « Imaginary Potential
- An important proof of the QCD theory is provided by the collisions between electrons and their antiparticles, positrons, with very high kinetic energy, when they annihilate each other.
- The goal is to study lots of processes, but most significantly to create really hot, dense conditions where we may be able to observe a phase transition in QCD to something called the quark-gluon plasma. Progress in QCD Pheno for RHIC? « Imaginary Potential
- There is also the axion particle issue, putative small mass particles which “protect” QCD from CP violations. A Dark, Misleading Force
- Strings are similar to mesons, where an open string with its endpoints, or Chan-Paton factors, are similar to a QCD gluon flux tube with quarks at the end. Astronomy Without A Telescope – Home Made Quark-Gluon Soup | Universe Today
- However, I find to stomach arguments that other completely useless things – like calculating the QCD beta function to n loops, or calculating the homotopy groups of spheres is somehow more worthy. What is String Theory Good For (Part I)? « Imaginary Potential
