What are Quarks made of and will they ever decay to this?
A top quark for example can decay through the weak interaction into a W-boson and another, lighter quark (bottom, down or strange). Up and down quarks can decay into each other by emission of a W boson (this is the origin of beta decay due to the fact that the W can, depending on its type, decay into electrons, positrons and electron (anti ...
energy conservation - How does an up quark decay into products …
2020年6月26日 · A bare single up-quark could not decay into a down-quark, as this would indeed voilate energy-mass conservation. A transition to a down-quark could happen within some interaction with another particle.

What is beta decay in terms of quarks? - Socratic
2016年6月6日 · 1 Answer. In β-decay, a quark decays into another type of quark, releasing a β particle and a neutrino. Protons and neutrons consist of quarks. (from quantumpulse.com) A proton consists of two up quarks and a down quark (p = uud). In positron (β+) decay, an up quark changes to a down quark, with the release of a positron and a neutrino.
particle physics - Can the $W^+$ boson couple an antistrange …
2021年5月31日 · It is correct , see this table of quark decays: In general, there exists a particle->antiparticle symmetry in the interactions, no separate tables are given for the decays . The table of elementary particles for example is by default followed with the antiparticle table, without need to write it expliscitly.
standard model - Chirality vs Helicity in Top Quark Decay - Physics ...
2022年2月20日 · Angular distributions from the decay leptons of W bosons in top quark decays at three individual helicities, compared to the standard model mixture. The helicity fractions are extracted from fits to angular distributions of the decay leptons of the respective W bosons. As an example, above are shown the results from 8 TeV data taken by CMS: F0 ...

particle physics - What dictates how the Higgs boson will decay ...
2018年9月2日 · 2. As far as I know the higgs boson has been observed to dacay into gamma ray photons, the Tau, b quark and maybe top quarks. But what are the factors that govern what particles it will decay to? And are there any other gauge bosons or fermions that the higgs boson might decay to in theory that have not been observed yet? particle-physics.
Finding out the Lifetimes/Decay Widths of Quarks?
2021年2月6日 · 1. Usually, PDG has the lifetimes/decay widths of all kinds of particles. However, for quarks, they don't seem to be there, not even in this 2014 PDG Quarks Review (except for the top quark t t). But I read that e. g. the bottom quark has …
What makes strange quarks stranger than any other quark?
2018年8月20日 · The concept of strangeness was invented before the strange quark was even imagined. Strangeness was originally conceived as a property of mesons to explain why some mesons decay much more slowly than others (and hence looked strange). The idea is that strangeness is a quantum number that is nearly conserved, which slows down the decays of ...
