Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Recently, the CDF and D0 collaborations measured indirect CP violation in B→ J/uψoφf and found a hint of a signal. If taken at face value, this can be interpreted as a nonzero phase of B -B mixing (βs), in disagreement with the standard model, which predicts that βs → 0. In this paper, we argue that this analysis may be incomplete. In particular, there can be new physics (NP) in the b → s̄c̄c decay. If so, the value of βs is different than for the case in which NP is assumed to be present only in the mixing. We have examined several models of NP and found that, indeed, there can be significant contributions to the decay. These effects are consistent with measurements in B → J/uπK* and B → J/uπKS. Due to the NP in the decay, polarization-dependent indirect CP asymmetries and triple-product asymmetries are predicted in B → Juπoφf. © SISSA 2010.
