We study charm production in charged-current deep-inelastic scattering (DIS) using the xFitter framework. Recent results from the LHC have focused renewed attention on the determination of the strange-quark parton distribution function (PDF), and the DIS charm process provides important complementary constraints on this quantity. We examine the current PDF uncertainty and use LHeC pseudodata ...Analogously, the five flavour quantum numbers (isospin, strangeness, charm, bottomness or topness) can characterize the quantum state of quarks, by the degree to which it exhibits six distinct flavours (u, d, s, c, b, t). Conspiracy theories, UFO sightings, ex-employee confessions, secret tunnels — there’s no shortage of Area 51 controversies. While some of the conspiracy theories are extremely far-fetched, others might make some sense.Subatomic particle - Quarks, Hadrons, Leptons: The discovery of the pion in 1947 seemed to restore order to the study of particle physics, but this order did not last long. Later in the year Clifford Butler and George Rochester, two British physicists studying cosmic rays, discovered the first examples of yet another type of new particle. The new particles were heavier than the pion or muon ...The City of the Dead is very much alive in Cairo.

A supermultiplet of baryons that contain the up, down, strange and charm quarks with half-spin. Charm quarks can exist in either "open charm particles", which contain one or several charm quarks, or as charmonium states, which are bound states of a charm quark and a charm antiquark. [64] The pyramids were built by the Egyptians during periods between inundation. There's an excellent audio book by Bob Briar if you're interested who gives some really interesting lectures on ancient Egypt. The flavours of quarks are up, down, top (or truth), bottom (or beauty), charm and strange. Physics gets weirder the smaller you go.weak decays, mediated by a W -boson, into a strange or down quark. An exception to this are decays of ground state charmonium mesons, which decay via annihilation of the charm and anti-charm quarks. Thus, open charm particles are the only ones allowing the study of weak decays of an up-type quark in a bound state.leads to the possibility of charm stars, i.e. self-bound strange stars with some amount of charm quarks in their cores. However, in spite of some constraints on their existence [1, 2], they might still occur in ultradense hybrid neutron stars.

The notion of color charge is proposed by Greenberg. A fourth quantum number dubbed "charm" was proposed by Bjorken and Glashow to counterbalance the "strangeness" carried by the strange quark. Nambu and and Han describe the SU(3) symmetry for quarks.Bacteria may seem like a strange ally in the battle against cancer. But in a new study, genetically engineered bacteria were part of a tag-team therapy to shrink tumors. In mice with blood, breast, or colon cancer, the bacteria acted as homing beacons for their partners—modified T cells—as the two sought out and destroyed tumor cells.They are named up, down, charm, strange, top, and bottom. Quarks are the only elementary particles to experience all the known forces of nature and to have a fractional electric charge. The interaction between quarks and gluons is responsible for almost all the perceived mass of protons and neutrons and is therefore where we get our mass.
