Search for Darkonium in e+ee+e Collisions / BABAR Collaboration
Collider searches for dark sectors, new particles interacting only feebly with ordinary matter, have largely focused on identifying signatures of new mediators, leaving much of dark sector structures unexplored. In particular, the existence of dark matter bound states (darkonia) remains to be investigated. [...]

Measurement of CPCP asymmetries in D±ηπ± and D±sηπ± decays / LHCb Collaboration
A search for CP violation in D±ηπ± and D±sηπ± decays is performed using proton-proton collision data, corresponding to an integrated luminosity of 3 fb1, recorded by the LHCb experiment at centre-of-mass energies of 7 and 8 TeV. The measured CP-violating charge asymmetries are ACP(D±ηπ±)=(0.61±0.72±0.53±0.12)% and ACP(D±sηπ±)=(0.82±0.36±0.22±0.27)%, where the first uncertainties are statistical, the second systematic, and the third are the uncertainties on the ACP(D±K0Sπ±) and ACP(D±sϕπ±) measurements used for calibration.

Measurement of the b-quark production cross-section in 7 and 13 TeV pp collisions / LHCb Collaboration
Measurements of the cross-section for producing b quarks in the reaction ppb¯bX are reported in 7 and 13TeV collisions at the LHC as a function of the pseudorapidity η in the range 2<η<5 covered by the acceptance of the LHCb experiment. The measurements are done using semileptonic decays of b-flavored hadrons decaying into a ground-state charmed hadron in association with a muon. [...]

Search for CP violation in the phase space of D0π+ππ+π decays / LHCb Collaboration
A search for time-integrated CP violation in the Cabibbo-suppressed decay D0π+ππ+π is performed using an unbinned, model-independent technique known as the energy test. This is the first application of the energy test in four-body decays. [...]

Measurements of charm mixing and CP violation using D0K±π decays / LHCb collaboration
Measurements of charm mixing and CP violation parameters from the decay-time-dependent ratio of D0K+π to D0Kπ+ decay rates and the charge-conjugate ratio are reported. The analysis uses ¯BD+μX, and charge-conjugate decays, where D+D0π+, and D0Kπ±. [...]
