Quark (dairy product) manufactured by "Dairyland". Quark may also be available as "baking cheese", "pressed cottage cheese", or "fromage frais". In Australia, Ukrainian traditional quark is produced by Blue Bay Cheese in Mornington Peninsula. It is also sometimes available from supermarkets labelled as quark or quarg. In New Zealand, European traditional Kwark is produced by Karikaas in North Canterbury. It is available in 350g pots and available online and in speciality stores such as Moore Wilsons. In the United Kingdom, fat-free quark is produced by several independent manufacturers based throughout the country. All the big four supermarkets in the UK sell their own
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
