Quark Techfest was created in 2006. It is an annual international technical festival organized by the Indian Institute of Technology in Delhi, India.
An antibottom quark (or b-bar quark) is the antiparticle of a bottom quark. It has the same mass as a bottom quark but opposite electric charge and other quantum numbers. When a bottom quark meets an antibottom quark, they can annihilate each other and produce energy.
Neutral pions are composed of a quark-antiquark pair, specifically an up quark and an anti-up quark or a down quark and an anti-down quark. They are the lightest mesons and are unstable, decaying rapidly into two photons.

The six quark flavors are up, down, strange, charmed, bottom, and top. The top quark was the last to be created in an accelerator since its mass was so great; after a nearly 20 year search it finally was announced by Fermilab.
If a meson were made up of a quark and an antiquark with different colors but the antiquark's color was not the anticolor of the quark, then the meson would not be color-neutral overall. This configuration would violate the requirement for color neutrality in hadrons as defined by quantum chromodynamics.

An anti-down quark is the antimatter counterpart of a down quark, one of the elementary particles that make up protons and neutrons in the atomic nucleus. It has opposite electric charge to a down quark and can combine with other quarks to form antimatter particles.
To Be a Lady was created in 1934.
