quark
noun
ˈkwȯrk 
ˈkwärk
ˈkwärk : any of several elementary particles that are postulated to come in pairs (as in the up and down varieties) of similar mass with one member having a charge of +²/₃ and the other a charge of −¹/₃ and are held to make up hadrons

Recent Examples on the Web Forte — the lead author of a paper published earlier this month in the journal Nature, describing the research — and his team set out to discover if the lightest of these heavier quarks, the charm quark, is present in the proton. 
Robert Lea, Popular Mechanics, 30 Aug. 2022 But while theorists had various reasons to expect the top quark and the Higgs to exist, and to be connected to the W boson through the equations of the Standard Model, today the theory has no obviously missing pieces. Charlie Wood, Quanta Magazine, 7 Apr. 2022 Filling: 4 gelatine sheets, 500g fat-free quark, 400g Philadelphia Lightest cream cheese (or other low-fat cream cheese), 100g zero-calorie granulated white sugar replacer, 45g Lotus Biscoff smooth spread, 1 tsp vanilla extract, 100ml soy milk. Elijah Rawls, Men's Health, 10 May 2022 In Wednesday's issue of Nature, a new paper describes a potentially useful way of measuring the interactions between normal matter and exotic particles, like antiprotons and unstable items like kaons or elements containing a strange quark. John Timmer, Ars Technica, 16 Mar. 2022 For example, a meson could consist of a red and an antired quark. Elizabeth Fernandez, Forbes, 19 Sep. 2021 The filling is made with low-fat quark instead of cream cheese and egg foam is added to give it more fluff, plus lemon and vanilla for some extra freshness. Marcel Krueger, CNN, 22 Oct. 2021 In the 1990s, Fermilab’s Tevatron, an enormous energy upgrade over the original main ring, discovered top quarks: the final quark in the Standard Model. Ethan Siegel, Forbes, 7 Sep. 2021 As correctly stated elsewhere in the obituary, it is known as a charm quark, not charmed. New York Times, 13 Aug. 2021 See More
