Quark (dairy product) then known as "syrniki". In Latvia, quark is eaten savory mixed with sour cream and scallions on rye bread or with potatoes. In desserts, quark is commonly baked into "biezpiena plātsmaize", a crusted sheet cake baked with or without raisins. A sweetened treat "biezpiena sieriņš" (small curd cheese) is made of small sweetened blocks of quark dipped in chocolate. Estonian Quark is evaluated on olfaction, vision, taste, after taste, and texture and is distributed nationally as well as to nearby regions. Although common in continental Europe, manufacturing of quark is rare in the Americas. A few dairies manufacture it, such
Constituent quark the constituent quark mass. Note that the following values are model dependent. Constituent quark A constituent quark is a current quark with a notional "covering" induced by the renormalization group. In the low energy limit of QCD, a description by means of perturbation theory is not possible: Here, no asymptotic freedom exists, but collective interactions between valence quarks and sea quarks gain strongly in significance. Part of the effects of virtual quarks and virtual gluons in the 'sea' can be assigned to a quark so well, that the term 'constituent quark' can serve as an effective description of the low
