“…Charm's first time was the discovery of the J/ψ 2,3 , which followed three years after the possible first observation of an open charm decay in cosmic ray showers 4 . This discovery confirmed the existence of a fourth quark as expected by the GIM mechanism 5 motivated by the non-existence of flavour-changing neutral currents 6,7 in conjunction with the observation of the mixing of neutral kaons 8,9,10 . The second time charm attracted considerable attention was caused by the observation of D sJ states 11,12,13,14 which could not be accommodated by QCD 15,16,17,18,19 .…”

Charm physics has attracted increased attention after first evidence for charm mixing was observed in 2007. The level of attention has risen sharply after LHCb reported first evidence for CP violation in the charm sector. Neither mixing nor CP violation have been established by a single unambiguous measurement to date. This review covers the status of mixing and CP violation measurements and comments on the challenges on the road ahead, both on the experimental and theoretical side, and on ways to tackle them.

“…The charge asymmetry 6z, should be given by 61, =2 I I~B ec, where x is the ratio of the AQ =-AS amplitude to the b Q =+AS amplitude in the semileptonic decay. Evidence strongly favors x --0; see Niebergall et al (1974).…”

The greatest pleasure a sc ientist can expe r ience is to encounter an unexpected discovery. I am always astonished when a simple apparatus, designed to ask the right question of nature, receives a clear response. Our experiment, carried out with James Christenson, Val Fitch, and Rene Turlay, gave convincing evidence that the long-lived neutral K meson (K~) decayed into two charged pions, a decay mode forbidden by CI' symmetry. The forbidden decay mode was found to be

This paper gives an overview of charm physics. It is a lecture write-up aimed at students with a minimum of prior knowledge in particle physics, but at the same time provides a state-of-the art review of the field. The main focus is on mixing and CP violation, which is a field with ever growing attention since first evidence for charm mixing was observed in 2007. Other areas covered are charm spectroscopy, production, as well as rare decays. Flavorful Ways to New Physics
