It is demonstrated that for a determination of the mass difference of the [Formula: see text] and [Formula: see text] mesons an explicit theoretical formula to be derived by an assumption of the CP-conservation has been used by CPLEAR Collaboration in a fitting of the time-dependent CPLEAR data on ASYMMETRY. So, in such procedure the mass difference [Formula: see text] of the [Formula: see text] and [Formula: see text] mesons has been found and in no case [Formula: see text] one as in this case the CP-violation has to be considered.

Wrong Sign

We report the recent results of [Formula: see text] mixing and CP violation studies in D0 decays from Belle, which include the time-dependent measurements of D0 wrong-sign semileptonic decay, wrong-sign hadronic decay to K+π-, as well as the wrong-sign ratio of hadronic decays to K+π-n(π).

Decay Parameters

A measurement of [Formula: see text] decay parameters using data collected by the ATLAS detector in [Formula: see text] collisions at 13 TeV in 2015–2017 is performed. Integrated luminosity of this sample is 80.5 fb[Formula: see text]. The measurement of physical parameters are statistically combined with results obtained from Run 1 data at 7 and 8 TeV. The measured value of CP-violating phase [Formula: see text] is obtained, which has significantly better precision in comparison with Run 1 result. Precision of other physical parameters is also improved, including the decay width difference [Formula: see text]. Further improvement is expected from the use of full Run 2 statistics, as well as from modifications in the analysis.

The LHCb experiment has been able to collect the largest sample ever produced of charm-hadron decays, performing a number of measurements of observables related to CP violation in the charm sector. In this document, the most recent results from LHCb on the search of direct CP violation in D0→Ks0Ks0, D(s)+→h+π0 and D(s)+→h+η decays are summarised, in addition to the most precise measurement of time-dependent CP asymmetry in D0→h+h− decays and the first observation of mass difference between neutral charm-meson eigenstates.

Abstract The teleseismic long-period waveforms recorded by the Global Digital Seismograph Network from the two largest Superstition Hills earthquakes are inverted using an algorithm based on optimal filter theory. These solutions differ slightly from those published in the Preliminary Determination of Epicenters Monthly Listing because a somewhat different, improved data set was used in the inversions and a time-dependent moment-tensor algorithm was used to investigate the complexity of the main shock. The foreshock (origin time 01:54:14.5, mb 5.7, Ms 6.2) had a scalar moment of 2.3 × 1025 dyne-cm, a depth of 8 km, and a mechanism of strike 217°, dip 79°, rake 4°. The main shock (origin time 13:15:56.4, mb 6.0, Ms 6.6) was a complex event, consisting of at least two subevents, with a combined scalar moment of 1.0 × 1026 dyne-cm, a depth of 10 km, and a mechanism of strike 303°, dip 89°, rake −180°.
