Quark (dairy product) these products are obtained by straining yogurt (milk fermented with thermophile bacteria), quark is made from soured milk fermented with mesophile bacteria. Quark is possibly described by Tacitus in his book "Germania" as "lac concretum" ("thick milk"), eaten by Germanic peoples. However, this could also have meant soured milk or any other kind of fresh cheese or fermented milk product. Although quark is sometimes referred to loosely as a type of "cottage cheese", they can be distinguished from the different production aspects and textural quality, with the cottage cheese grains described as more chewy or meaty. The word "Quark" (Late
Top quark generated by the Higgs. The slight growth is due to corrections from the QCD coupling. The corrections from the Yukawa couplings are negligible for the lower mass quarks. If, however, a quark Yukawa coupling has a large value at very high energies, its Yukawa corrections will evolve and cancel against the QCD corrections. This is known as a (quasi-) infrared fixed point. No matter what the initial starting value of the coupling is, if it is sufficiently large it will reach this fixed point value. The corresponding quark mass is then predicted. The top quark Yukawa coupling lies very near
