Summary
This summary is machine-generated.

Evidence for D0-D(0) mixing in D(0) decays to K(+)pi(-) was found using BABAR detector data. This observation, inconsistent with no-mixing, suggests new physics beyond the Standard Model may be at play.

Area of Science:

  • Particle Physics
  • High Energy Physics
  • Quantum Mechanics

Background:

  • The Standard Model of particle physics describes fundamental particles and forces.
  • D0 mesons are subatomic particles that can decay into other particles.
  • D0-D(0) mixing is a phenomenon where a D0 meson oscillates into its antiparticle, the anti-D0 meson.

Purpose of the Study:

  • To investigate evidence for D0-D(0) mixing in D(0) --> K(+)pi(-) decays.
  • To measure the mixing parameters x' and y'.
  • To determine the ratio of doubly Cabibbo-suppressed to Cabibbo-favored decay rates, R(D).

Main Methods:

  • Analysis of 384 fb(-1) of e(+)e(-) colliding-beam data.
  • Utilized the BABAR detector at the PEP-II storage rings.

Related Experiment Videos

  • Statistical analysis to determine mixing parameters and decay rate ratios.

    • Main Results:

    • Observed D0-D(0) mixing with a significance of 3.9 standard deviations.
    • Measured mixing parameters x'2 = [-0.22 +/- 0.30(stat) +/- 0.21(syst)] x 10(-3) and y' = [9.7 +/- 4.4(stat) +/- 3.1(syst)] x 10(-3).
    • Measured R(D) = [0.303 +/- 0.016(stat) +/- 0.010(syst)]% and found no evidence for CP violation.

    Conclusions:

    • The observed D0-D(0) mixing provides evidence for physics beyond the Standard Model.
    • The measured parameters are inconsistent with the no-mixing hypothesis.
    • Further investigation into CP violation in D0 decays is warranted.
