    • Holographic entanglement entropy for perturbative higher-curvature gravities 

      Bueno, Pablo; Camps, Joan; Vilar López, Alejandro (Springer, 2021)
      The holographic entanglement entropy functional for higher-curvature gravities involves a weighted sum whose evaluation, beyond quadratic order, requires a complicated theory-dependent splitting of the Riemann tensor ...
    • The nature of X(3872) from high-multiplicity pp collisions 

      Esposito, Angelo; González Ferreiro, Elena; Pilloni, Alessandro; Polosa, Antonio Davide; Salgado López, Carlos Alberto (Springer, 2021)
      The structure of exotic resonances that do not trivially fit the usual quark model expectations has been a matter of intense scientific debate during the last two decades. A possible way of estimating the size of these ...
    • Entanglement entropy in cubic gravitational theories 

      Cáceres, Elena; Castillo Vásquez, Rodrigo; Vilar López, Alejandro (Springer, 2021)
      We derive the holographic entanglement entropy functional for a generic gravitational theory whose action contains terms up to cubic order in the Riemann tensor, and in any dimension. This is the simplest case for which ...
    • Interacting color strings as the origin of the liquid behavior of the quark-gluon plasma 

      Ramírez, Jhony; Díaz, Bogar; Pajares Vales, Carlos (APS Physics, 2021)
      We study the radial distribution function of the color sources (strings) formed in hadronic collisions and the requirements to obtain a liquid. As a repulsive interaction is needed, we incorporate a concentric core in the ...
    • Searches for 25 rare and forbidden decays of D+ and D+s mesons 

      LHCb Collaboration; Adeva Andany, Bernardo; Alves Junior, Antonio Augusto; Baladrón Rodríguez, Pablo; Boente García, Óscar; Brea Rodríguez, Alexandre; Casais Vidal, Adrián; Chobanova, Veronika; Cid Vidal, Xabier; Dalseno, Jeremy; Dieste Maroñas, Lorena; Fernández Prieto, Antonio; Gallas Torreira, Abraham Antonio; García Plana, Beatriz; Gioventù, Alessandra; Lomba Castro, Julián; Martínez Santos, Diego; Parkinson, Chris J.; Plo Casasus, Máximo; Prouve, Claire; Ramos Pernas, Miguel; Romero Lamas, Marcos; Romero Vidal, Antonio; Saborido Silva, Juan José; Santamarina Ríos, Cibrán; Vázquez Regueiro, Pablo (Springer, 2021)
      A search is performed for rare and forbidden charm decays of the form D+(s)→h±ℓ+ℓ(′)∓, where h± is a pion or kaon and ℓ(′)± is an electron or muon. The measurements are performed using proton-proton collision data, ...
