Hadronic nature of high-energy emission from the Galactic ridge

Andrii Neronov

We show that the IceCube observation of the Galactic neutrino-flux component confirms the hint of detection of neutrinos from the Galactic ridge (the inner part of the Milky Way disk within the Galactic longitude IlI < 30(degrees)), previously reported by ...

Extended Scalar Sectors

Jan Steggemann

Extended scalar sectors appear in various extensions of the Standard Model of particle physics, such as supersymmetric models. They are also generic extensions of the Standard Model and can address a number of its shortcomings. Direct searches for addition ...

The results of a search for the rare two-body charmless baryonic decays B-0 -> p (p) over bar and B-s(0) -> p (p) over bar are reported. The analysis uses a data sample, corresponding to an integrated luminosity of 0.9 fb(-1), of p p collision data collect ...

NLO QCD corrections to five-jet production at LEP and the extraction of alpha(s)(M-Z)

The highest exclusive jet multiplicity studied at LEP experiments is five. In this paper we compute the next-to-leading order QCD corrections to e(+)e(-) annihilation to five jets, essentially closing the (pure) perturbative QCD studies of exclusive jetty ...

Dalitz analysis of B→Kπ+ψ′ decays and the Z(4430)

Mingkui Wang, Olivier Schneider, Chao Wang, Aurelio Bay, Vladislav Balagura, Remi Léandre Albert Louvot

From a Dalitz plot analysis of B→Kπ+ψ′ decays, we find a signal for Z(4430)+→π+ψ′ with a mass M=(4443-12-13+15+19)MeV/ c2, width Γ=(107-43-56+86+74)MeV, product branching fraction B(B̄0→K-Z(4430)+)×B(Z(4430)+→π+ψ′)=(3.2-0.9-1. 6+1.8+5.3)×10-5, and signific ...
