Brief Review of Charm Physics

Abstract

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.

CPviolation in theBsystem

“…[16][17][18][19][20]. The reader may also be interested in recent reviews on kaon [21,22] or charm [23,24] physics, on the strong CP problem [25,26] and searches for electric dipole moments [27], or on prospects for CP violation measurements in the lepton sector [28,29].…”

“…Indeed, the large number of X, Y, Z states being reported experimentally [1][2][3][4] are finding difficulties to be fitted in the ordinary order of standard charmonium states [5] and call for more complex structures. The molecular picture of states coming from the interaction of D orD * has been one of the sources to interpret some of these states, and different combinations of such mesons giving hidden charm mesons have been considered.…”

Masses of di-mesonic molecular states

“…The world wide experimental facilities like BES, Belle, BaBar, CLEO have provided the new data (states) in the field of hadron physics especially in the light quark sector [1][2][3][4]. These new states are not only light flavor mesons and baryons but demands new explanation like tetra quark, pentaquark, hexaquark or molecular like descriptions while some of states are having more complex structure.…”
