The CKM angle γγ is measured for the first time from mixing-induced CPCP violation between B0s→D∓sK±π±π∓Bs0→Ds∓K±π±π∓ and B¯0s→D±sK∓π∓π±B¯s0→Ds±K∓π∓π± decays reconstructed in proton-proton collision data corresponding to an integrated luminosity of 9 fb−1fb−1 recorded with the LHCb detector. A time-dependent amplitude analysis is performed to extract the CPCP-violating weak phase γ−2βsγ−2βs and, subsequently, γγ by taking the B0sBs0-B¯0sB¯s0 mixing phase βsβs as an external input. The measurement yields γ=(44±12)∘γ=(44±12)∘ modulo 180∘180∘, where statistical and systematic uncertainties are combined. ...

Long-lived particles decaying to e±μ∓νe±μ∓ν, with masses between 7 and 5050 GeV/c22 and lifetimes between 2 and 5050 ps, are searched for by looking at displaced vertices containing electrons and muons of opposite charges. The search is performed using 5.45.4 fb−1−1 of pppp collisions collected with the LHCb detector at a centre-of-mass energy of s√=13s=13 TeV. Three mechanisms of production of long-lived particles are considered: the direct pair ...

Using pppp collision data corresponding to an integrated luminosity of 5.4fb−15.4fb−1 collected with the LHCb detector at a center-of-mass energy of 13TeV13TeV, the B0→D−D+K+π−B0→D−D+K+π− decay is studied. A new excited D+sDs+ meson is observed decaying into the D+K+π−D+K+π− final state with large statistical significance. The pole mass and width, and the spin-parity of the new state are measured with an amplitude analysis to be mR=2591±6±7MeVmR=2591±6±7MeV, ΓR=89±16±12MeVΓR=89±16±12MeV and JP=0−JP=0−, where the ...

Charmed hadrons are a unique probe of CP violation with up-type quarks. Yet, CPviolation in the charm sector is very suppressed by tiny CKM phases in the Standard Model. Any large non-zero measurement would thus be a sign of New Physics. We report on recent measurements of CP asymmetries in multibody charmed meson and baryon decays. The CP asymmetries are studied in ...

The Λ0b→Λ+cK+K−π−Λb0→Λc+K+K−π− decay is observed for the first time using a data sample of proton-proton collisions at centre-of-mass energies of s√=7s=7 and 8 TeVTeV collected by the LHCbLHCb detector, corresponding to an integrated luminosity of 3fb−13fb−1. The ratio of branching fractions between the Λ0b→Λ+cK+K−π−Λb0→Λc+K+K−π− and the Λ0b→Λ+cD−sΛb0→Λc+Ds− decays is measured to be
B(Λ0b→Λ+cK+K−π−)B(Λ0b→Λ+cD−s)=(9.26±0.29±0.46±0.26)×10−2,B(Λb0→Λc+K+K−π−)B(Λb0→Λc+Ds−)=(9.26±0.29±0.46±0.26)×10−2,

A first search for CPCP violation in the Cabibbo-suppressed Ξ+c→pK−π+Ξc+→pK−π+ decay is performed using both a binned and an unbinned model-independent technique in the Dalitz plot. The studies are based on a sample of proton-proton collision data, corresponding to an integrated luminosity of 3.0fb−13.0fb−1, and collected by the LHCb experiment at centre-of-mass energies of 7 and 8TeV8TeV. The data are consistent ...

Exploring life cycles of fungi is insightful for understanding their basic biology and can highlight their ecology. Here, we dissected the sexual and asexual life cycles of the obligate alkalophilic ascomycete Sodiomyces alkalinus that thrives at extremely high pH of soda lakes. Sodiomyces alkalinus develops acremonium-type asexual sporulation, commonly found in ascomycetous fungi. However, the ...

In this short review, we first discuss the results, which are mainly devoted to the generalizations of the famous Kohn–Luttinger mechanism of superconductivity in purely repulsive fermion systems at low electron densities. In the context of repulsive-U Hubbard model and Shubin–Vonsovsky model we consider briefly the superconducting phase diagrams and the symmetries of the order parameter ...

The framework of simple opposition realism - anti-realism is not enough to analyze the views on the reality of unobservable objects of quantum theory. First, it is necessary to distinguish between realism in relation to the theory and realism in relation to the theory’s objects. Secondly, realism in relation to classical objects can be combined, ...
