Quark (dairy product) Quark (dairy product) Quark or quarg is a type of fresh dairy product made by warming soured milk until the desired amount of curdling is met, and then straining it. It can be classified as fresh acid-set cheese. Traditional quark can be made without rennet, but in modern dairies small quantities of rennet are typically added. It is soft, white and unaged, and usually has no salt added. It is traditional in the cuisines of German-speaking, Slavic and Scandinavian countries. Dictionaries sometimes translate it as curd cheese, cottage cheese, farmer cheese or junket. In Germany, quark and cottage cheese are
Current quark the formula_1-Scheme at formula_2 the quark masses are: A description is only possible with the help of relativistic quantum mechanics. The current quark mass is also called the mass of the 'naked' quarks. The mass of the current quark is reduced by the term of the constituent quark covering mass. The current quark mass is a logical consequence of the mathematical formalism of the quantum field theory (QFT), thus it is from a not descriptive origin. The current quark masses of the light current quarks are much smaller than the constituent quark masses. Reason for this is the missing of
