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
Top quark decays, but only at one loop level, meaning that they are extremely suppressed. In particular, it is possible for a top quark to decay into another up-type quark (an up or a charm) by emitting a photon or a Z-boson. Searches for these exotic decay modes have provided no evidence for their existence in accordance with expectations from the Standard Model. The branching ratios for these decays have been determined to be less than 5.9 in 1,000 for photonic decay and less than 2.1 in 1,000 for Z-boson decay at 95% confidence. The Standard Model describes fermion masses through the
