Observation of a narrow pentaquark state, $P_{c} (4312)^{+}$ , and of two-peak structure of the $P_{c} (4450)^{+}$

LHCb collaboration, R. Aaij, C. Abellán Beteta +866

A narrow pentaquark state, $P_{c} (4312)^{+}$ , decaying to $J / ψ p$ is discovered with a statistical significance of $7.3 σ$ in a data sample of $Λ_{b}^{0} \to J / ψ p K^{-}$ decays which is an or…

Introduction of total variation regularization into filtered backprojection algorithm

L. Raczyński, W. Wiślicki, K. Klimaszewski +30

In this paper we extend the state-of-the-art filtered backprojection (FBP) method with application of the concept of Total Variation regularization. We compare the performance of t…

Measurement of the $B^{\pm}$ production cross-section in pp collisions at $s =$ 7 and 13 TeV

LHCb collaboration, R. Aaij, B. Adeva +796

The production of $B^{\pm}$ mesons is studied in $pp$ collisions at centre-of-mass energies of 7 and 13 TeV, using $B^{\pm} \to J / ψ K^{\pm}$ decays and data samples correspon…

$χ_{c 1}$ and $χ_{c 2}$ resonance parameters with the decays $χ_{c 1, c 2} \to J / ψ μ^{+} μ^{-}$

LHCb collaboration, R. Aaij, B. Adeva +797

The decays $χ_{c 1} \to J / ψ μ^{+} μ^{-}$ and $χ_{c 2} \to J / ψ μ^{+} μ^{-}$ are observed and used to study the resonance parameters of the $χ_{c 1}$ and $χ_{c 2}$ mesons. The mass…
