Rough Outline Some Background Comments Some Standard Model Some New Physics

‘Coals to Newcastle’ Experiment CLEO: Bonvicini, Cinabro, Dubrovin CDF: Harr, Karchin Theory Petrov, Gabbiani, AlFiky

Discovery of Charm Age: c-quark will turn 31 on 11/11 Birth: East Coast (BNL) West Coast (SLAC) SLAC Method: Narrow resonance at E = 3.1 GeV! Thereafter called the `J/  ’

The Standard Model

NuTeV Anomaly?

Three Years of Tests

Spectrum of Quark Masses Predict this Spectrum: Easy/Hard?

Quark Masses and Theory Predict quark masses? No viable models exist What about String Theory? String ground state huge! `Landscape’ description. Many-universes scenario. Elementary constants random! Lucky us! We EXIST!! What about m c = 1.3 GeV? Difficult theoretically. Not heavy enough! Not light enough! Complications of QCD

QED vs QCD QED QCD

Progress in Lattice QCD

Standard Model Physics D Meson Ground State The spectator c-quark: B c Mesons D Decays: Leptonic, Semileptonic, Nonleptonic Spectroscopy: Exotic states?

D Meson Ground State Predict the States: Easy/Hard?

D Meson Ground State q = u  D 0 q = d  D + q = s  D s + Easy! 3 * of SU(3)

Flavored Mesons Each quark has its own ‘flavor’ Quark composites are ‘flavored’ s-quark: K’s = c-quark: D’s = b-quark: B’s = The t-quark decays too quickly!

B c Mesons!

Leptonic Decay of D + Decay Amplitude: Decay Constant f D : Non-perturbative efect. Requires Lattice QCD!

f D : Theory vs Experiment

Semileptonic Decays Decay Amplitude: D 0  K e + e

Form Factor Slopes

Nonleptonic Decays Decay Amplitude: A = a e i 

Dalitz Studies

Phase Information

More Dalitz

Comparative Lifetimes B: B - = b B 0 = d  - /  0 = 0.92

Comparative Lifetimes B: B - = b B 0 = d  - /  0 = 0.92 D: D 0 = c D + = c  - /  0 = 2.55

Comparative Lifetimes B: B - = b B 0 = d  - /  0 = 0.92 D: D 0 = D + =  - /  0 = 2.55 K: K - = K 0 =  - /  0 = 139.

Charm Production e+e- collisions produce charm. There are predictions for this. Not all data are understood!

Heavy Meson Spectroscopy

X(3872) Sighting

Is X(3872) a Molecule? AlFiky, Gabbiani, Petrov (2005) [plus others] Interpret X(3872) as a bound state of hadrons ( ) Analogous to the Deuteron! Similar molecular state predicted long ago. Beware: other interpretations possible.

Y(3940)  2 /d.o.f. = 15.6/8 stat. sig. = 8.1   above D*D threshold  not found in DD or D*D final states

Is Y(3940) a ‘Hybrid’? Hybrid Meson : Color-octet quark-antiquark couples to color-octet gluon to yield color-singlet hadron

D 0  K -  +

Where are CP Violations?

New Physics and Charm Methodology? Rare Decays of D Mesons Flavor Oscillations CP Violations (not discussed here)

Methodology How to find ‘New Physics’? Study systems where SM signals are small. Ideal for charm: A] Rare Decays B] Flavor Oscillations

D 0   +  - in the SM

Data and D 0   +  -

D 0   0 e + e -

Flavor Oscillations Mixing Mixing also in K 0,B d and B s. Each of these is different!

Two Coupled Penduli

The ‘Spring’

New Physics and Mixing

The Normal Modes Normal Modes Effect of CP: CP EigenstatesCP Eigenstates

Mixing of B d Mesons

Mixing of B s Mesons

Mixing of K Mesons

Mixing of D 0 Mesons

Recent Work on D 0 Mixing Theory: Effect of QCD incorporated into analysis of D 0 mixing by Golowich and Petrov. Work continues. Experiment; Especially interesting are attempts to measure  D at the 1% level.

Summary I The c-quark is a remarkably spry 31 year old! A very active social life: Spectroscopy Flavor oscillations Rare decays CP violation searches After studies at CDF, CLEO, Belle and BaBar will come the long awaited LHC.

Summary II Flavor mixing of D mesons will be a hot topic for both experimenters and theorists. Exotic charm states (hybrid and/or molecular) will continue to attract much attention.
