We measure the charge asymmetry A ≡ (N++ - N--)/(N++ + N--) of like-sign dimuon events in 6.1 fb-1 of pp collisions recorded with the D0 detector at a center-of-mass energy square root(s) = 1.96   TeV at the Fermilab Tevatron collider. From A we extract the like-sign dimuon charge asymmetry in semileptonic b-hadron decays: A(sl)(b) = -0.009 57 ± 0.002 51(stat) ± 0.001 46(sys). It differs by 3.2 standard deviations from the standard model prediction A(sl)(b)(SM) = (-2.3(-0.6)(+0.5)) × 10(-4…

Recently, the DØ Collaboration measured the CP-violating like-sign dimuon charge asymmetry in neutral B decays, finding a 3.2σ difference from the standard-model (SM) prediction. Anon-SM charge
Measurement of the semileptonic charge asymmetry in $B^0$ meson mixing with the D0 detector
• Physics
• 2012
We present a measurement of the semileptonic mixing asymmetry for B0 mesons, a^d_{sl}, using two independent decay channels: B0 -> mu+D-X, with D- -> K+pi-pi-; and B0 -> mu+D*-X, with D*- -> antiD0
Background check for anomalous like-sign dimuon charge asymmetry
• Physics

The D0 Collaboration has reported an excess of roughly 1% of {mu}{sup -{mu}-} pairs over {mu}{sup +{mu}+} pairs in pp collisions at a center-of-mass energy {radical}(s)=1.96 GeV at the Fermilab
A possible explanation of the D0 like-sign dimuon charge asymmetry
• Physics

We reconsider the recent observation by the D0 experiment of a sizable like-sign dimuon charge asymmetry, highlighting that it could be affected by CP-violating New Physics contributions not only in
Z-mediated charge and CP asymmetries and FCNCs in Bd,s processes
• Physics

We show model-independently that the negative like-sign charge asymmetry (−Asℓb) is less than 3.16 × 10−3 when the constraints from the ${B_q} - {\bar{B}_q}$ mixings and the time-dependent CP
Like-Sign Dimuon Asymmetry of B0 Meson and LFV in SU(5) SUSY GUT with S4 Flavor Symmetry

• 2011
The like-sign dimuon charge asymmetry of the B meson, which was reported in the DO Collaboration, is studied in the SU(5) SUSY GUT model with S4 flavor symmetry. Additional CP violating effects from
Implications of large dimuon CP asymmetry in Bd,s decays on minimal flavor violation with low tan β
• Physics
• 2010
The D0 collaboration has recently announced evidence for a dimuon CP asymmetry in Bd,s decays of order one percent. If confirmed, this asymmetry requires new physics. We argue that for minimally

We confirm that in order to account for the recent D0 result of large like-sign dimuon charge asymmetry, a considerable large new physics effect in {Gamma}{sub 12}{sup s} is required in addition to a
