Understanding the 0 and 2 charmonium(-like) states near 3.9 GeV.

We propose that the X(3915) observed in the J/ψω channel is the same state as the χ(3930), and the X(3960), observed in the DD channel, is an S-wave DD hadronic molecule. In addition, the J=0 component in the B→DDK assigned to the X(3915) in the current Review of Particle Physics has the same origin as the X(3960), which has a mass around 3.94 GeV.

Interpretation of the LHCb P_{c}(4312)^{+} Signal.

We study the nature of the new signal reported by LHCb in the J/ψp spectrum. Based on the S-matrix principles, we perform a minimum-bias analysis of the underlying reaction amplitude, focusing on the analytic properties that can be related to the microscopic origin of the P_{c}(4312)^{+} peak. By exploring several amplitude parametrizations, we find evidence for the attractive effect of the Σ_{c}^{+}D[over ¯]^{0} channel, which is not strong enough, however, to form a bound state.

Prostate cancer screening: guidelines review and laboratory issues.

Background Prostate-specific antigen (PSA) remains as the most used biomarker in the detection of early prostate cancer (PCa). Clinical practice guidelines (CPGs) are produced to facilitate incorporation of evidence into clinical practice. This is particularly useful when PCa screening remains controversial and guidelines diverge among different medical institutions, although opportunistic screening is not recommended.

[Evolution in anthropometric variables related to training and nutritional parameters in ultra-endurance mountain runners].

Introduction: eating and training habits induce modifications in the anthropometric parameters. Objectives: to analyze the evolution of the anthropometric variables in the eleven previous weeks to the competition in recreational mountain runners and to identify the factors that could explain those changes. Methods: twenty-two recreational ultra-endurance mountain runners (mean age: 41.

Determination of the Pole Position of the Lightest Hybrid Meson Candidate.

Mapping states with explicit gluonic degrees of freedom in the light sector is a challenge, and has led to controversies in the past. In particular, the experiments have reported two different hybrid candidates with spin-exotic signature, π_{1}(1400) and π_{1}(1600), which couple separately to ηπ and η^{'}π. This picture is not compatible with recent Lattice QCD estimates for hybrid states, nor with most phenomenological models.
