  Aaij, Roel; Adeva Andany, Bernardo; Borsato, Martino; Chobanova, Veronika; Cid Vidal, Xabier; Dosil Suárez, Álvaro; Fernández Prieto, Antonio; Gallas Torreira, Abraham; García Pardiñas, Julián; Lemos Cid, Edgar; Lucio Martínez, Miriam; Martínez Santos, Diego; Plo Casasus, Máximo; Prisciandaro, Jessica; Ramos Pernas, Miguel; Romero Vidal, Antonio; Saborido Silva, Juan José; Sanmartín Sedes, Brais; Santamarina Ríos, Cibrán; Vázquez Regueiro, Pablo; Vieites Díaz, María; Vázquez Sierra, Carlos; LHCb Collaboration (Springer, 2017-10-13)

  A search for the decay K0S→μ+μ− is performed, based on a data sample of proton-proton collisions corresponding to an integrated luminosity of 3 fb −1 , collected by the LHCb experiment at centre-of-mass energies of 7 ...

• Observation of pentaquark resonances in Λb → J/ψK−p decays 

  Adeva, Bernardo (EDP Sciences, 2016-11-04)

  LHCb has recently reported the observation of exotic structures in the J/ψp channel, in Λb → J/ψK−p decay, which we discuss here and refer to as charmoniumpentaquarkstates. The data sample corresponds to an integrated ...

• An analysis of the impact of LHC Run I proton–lead data on nuclear parton densities 

  Armesto, Néstor; Paukkunen, Hannu; Penín, José Manuel; Salgado, Carlos A.; Zurita, Pía (Springer, 2016-04-21)

  We report on an analysis of the impact of available experimental data on hard processes in proton–lead collisions during Run I at the large hadron collider on nuclear modifications of parton distribution functions. Our ...

• Energy versus centrality dependence of the jet quenching parameter q̂ at RHIC and LHC: a new puzzle? 

  Andrés, Carlota; Armesto, Néstor; Luzum, Matthew; Salgado, Carlos A.; Zurita, Pía (Springer, 2016-08-26)

  The central goal of jet quenching studies in high-energy nuclear collisions is the characterization of those QCD medium properties that are accessible by these probes. Most of the discussion in the last years has been ...

• Dynamical effects in fission investigated at high excitation energy 

  Benlliure, Jose (EDP Sciences, 2016-05-11)

  The experimental techniques used for the investigation of nuclear fission have progressed considerably during the last decade. Most of this progress is based on the use of the inverse kinematics technique allowing for the ...
