Quark (dairy product) a somewhat crumbly texture (like ricotta). The basic quark this basic quark or skimmed quark ("Magerquark") must under German Law have less than 10% fat by dry mass. Quark with higher fat content is made by adding cream after cooling. It has a very smooth and creamy texture and is slightly sweet (unlike sour cream). A firmer version called "Schichtkäse" (layer cheese) is often used for baking. Schichtkäse is distinguished from quark by having an added layer of cream sandwiched between two layers of quark. Quark is also often sold flavored with herbs, spices, or fruit. In general, dry mass
Top quark condensate Top quark condensate In particle physics, the top quark condensate theory (or top condensation) is an alternative to the Standard Model fundamental Higgs field, replaced by a composite field of the top quark and its antiquark. These are bound together by a new force, analogous to the binding of Cooper pairs in a BCS superconductor, or mesons in the strong interactions. The top quark can "condense" because it is comparatively heavy, with a measured mass is approximately 173 GeV (comparable to the electroweak scale), and so its Yukawa coupling is of order unity, yielding the possibility of strong coupling dynamics.
