Entity: QCD
QCD, short for quantum chromodynamics, is a theory of strong interactions between elementary particles, assuming that particles are made of quarks and gluons. It also refers to qualified charitable distributions, allowing individuals aged 70½ or older to donate from their IRA directly to charities.
QCD
Etymology
The abbreviation QCD stands for quantum chromodynamics.
Definition
QCD refers to a theory of strong interactions between elementary particles, assuming that particles are made of quarks and gluons. It also denotes a qualified charitable distribution, enabling individuals aged 70½ or older to donate from their IRA directly to charities.
Historical Context
Quantum chromodynamics has been a fundamental theory in particle physics, explaining the strong force between quarks and gluons. Qualified charitable distributions have provided a tax-efficient way for older individuals to support charitable causes.
Cultural Significance
QCD has played a crucial role in understanding the structure of matter at the smallest scales, while qualified charitable distributions have facilitated philanthropic giving among retirees.
Related Concepts
Other related concepts include quantum mechanics, chromodynamics, elementary particles, hadrons, quarks, gluons, and charitable giving.
