The initialism QCD may refer to:
In theoretical physics, quantum chromodynamics (QCD) is the theory of strong interactions, a fundamental force describing the interactions between quarks and gluons which make up hadrons such as the proton, neutron and pion. QCD is a type of quantum field theory called a non-abelian gauge theory with symmetry group SU(3). The QCD analog of electric charge is a property called color. Gluons are the force carrier of the theory, like photons are for the electromagnetic force in quantum electrodynamics. The theory is an important part of the Standard Model of particle physics. A large body of experimental evidence for QCD has been gathered over the years.
QCD enjoys two peculiar properties:
The strongest force in the universe is the strong nuclear force and it governs the behavior of quarks and gluons inside protons and neutrons. The name of the theory that governs this force is quantum chromodynamics, or QCD. In this video, Fermilab’s Dr. Don Lincoln explains the intricacies of this dominant component of the Standard Model.

Wo oh oh
wo oh oh, wo oh oh oh
wo oh
Now baby I been thinking bout how you been acting strange
and baby I been thinking how so many things have changed
in my life, in my home, in my bed
said I remember how you used to love
How you used to love, you don't love no more
how you used to care, you don't care no more
that's alright, that's ok
drop the key on your way
catch a bus, ride the train
it doesn't matter just keep going
Now boy I can remember how I used to foot the bill
and yes I do regret the day I took your broke ass in
to my life, to my home, to my bed
said that I must have lost my head
I guess you thought that I'd let you walk on me like the floor
I gues you thought that you'd keep tracking dirt inside my door
you got it all wrong
it's been too long
all of the love is gone
now I'm singing you this song
How you used to love, you don't love no more
how you used to care, you don't care no more
that's alright, that's ok
drop the key on your way
grab a bus, ride the train
it doesn't matter just keep going
How you used to love, you don't love no more
how you used to care, you don't care no more
that's alright, that's ok
drop the keys on your way
grab a bus, ride the train
it doesn't matter just keep going
You must have thought that you were getting over for so long
but I was giving you the chance to make things right from being so wrong
but your time is up, took too long, I don't wanna hear it
get your shirt, shoes, pants and draws up from outta here
Oh oh oh oh
wo oh ooh wo
woo woo oh
Like you used to love, you don't love no more
how you used to care, you don't care no more
that's alright, that's ok
drop the keys on your way
grab a bus, ride the train
it doesn't matter just keep going
How you used to love, you don't love no more
how you used to care, you don't care no more
that's alright, that's ok
drop the keys on your way
grab a bus, ride the train
it doesn't matter just keep going
Oh oh oh
