    • PDF reweighting in the Hessian matrix approach 

      Paukkunen, Hannu; Zurita, María Pía (Springer, 2014)
      We introduce the Hessian reweighting of parton distribution functions (PDFs). Similarly to the better-known Bayesian methods, its purpose is to address the compatibil- ity of new data and the quantitative modifications ...
    • Precise measurements of the properties of the B1(5721)0,+ and B *2(5747)0,+ states and observation of B+,0π−,+ mass structures 

      LHCb Collaboration; Adeva Andany, Bernardo; Dosil Suárez, Álvaro; Fernández Albor, Víctor Manuel; Gallas Torreira, Abraham Antonio; García Pardiñas, Julián; Hernando Morata, José Ángel; Plo Casasus, Máximo; Romero Vidal, Antonio; Saborido Silva, Juan José; Sanmartín Sedes, Brais; Santamarina Ríos, Cibrán; Vázquez Regueiro, Pablo; Vázquez Sierra, Carlos; Vieites Díaz, María (Springer, 2015)
      Invariant mass distributions of B+π− and B0π+ combinations are investigated in order to study excited B mesons. The analysis is based on a data sample corresponding to 3.0 fb−1 of pp collision data, recorded by the LHCb ...
    • Production of associated Y and open charm hadrons in pp collisions at √s=7 and 8 TeV via double parton scattering 

      LHCb Collaboration; Dosil Suárez, Álvaro; Fernández Albor, Víctor Manuel; Gallas Torreira, Abraham Antonio; 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; Vázquez Sierra, Carlos; Vieites Díaz, María (Springer, 2016)
      Associated production of bottomonia and open charm hadrons in pp collisions at √s=7 and 8 TeV is observed using data corresponding to an integrated luminosity of 3 fb−1 accumulated with the LHCb detector. The observation ...
    • Quarkonium: a theory overview 

      González Ferreiro, Elena (Elsevier, 2019)
      Quarkonium has long been proposed as one of the golden probes to identify the phase transition from confined hadronic matter to the deconfined quark-gluon plasma in heavy-ion collisions. Since then, we have achieved a ...
    • Reggeon field theory for large Pomeron loops 

      Altinoluk, Tolga; Kovner, Alex; Levin, Eugene; Lublinsky, Michael (Springer, 2014)
      We analyze the range of applicability of the high energy Reggeon Field Theory HRFT derived in [1]. We show that this theory is valid as long as at any intermediate value of rapidity η throughout the evolution at least ...
    • String percolation in AA and p plus p collisions 

      Bautista Guzmán, Irais; Pajares Vales, Carlos; Ramírez Cancino, Jhony Eredi (Sociedad Mexicana de Física, 2019)
      A brief review of the string percolation model and its results are presented together with the comparison to experimental data. First, it is done an introduction to the quark-gluon phase diagram and the lattice results ...
    • Study of bb¯correlations in high energy proton-proton collisions 

      LHCb Collaboration; Adeva Andany, Bernardo; Borsato, Martino; Chobanova, Veronika; Cid Vidal, Xabier; Dosil Suárez, Álvaro; Fernández Prieto, Antonio; 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 (Springer, 2017)
      Kinematic correlations for pairs of beauty hadrons, produced in high energy proton-proton collisions, are studied. The data sample used was collected with the LHCb experiment at centre-of-mass energies of 7 and 8 TeV and ...
    • Study of the D0 p amplitude in Λ0b → D0 pπ − decays 

      LHCb Collaboration; Adeva Andany, Bernardo; Borsato, Martino; Chobanova, Veronika; Cid Vidal, Xabier; Dosil Suárez, Álvaro; Fernández Prieto, Antonio; Gallas Torreira, Abraham Antonio; 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 (Springer, 2017)
      An amplitude analysis of the decay Λ0b → D0 pπ − is performed in the part of the phase space containing resonances in the D0 p channel. The study is based on a data sample corresponding to an integrated luminosity of 3.0 ...
    • Study of η − η′ mixing from measurement of B 0(s) → J/ψη(′) decay rates 

      LHCb Collaboration; Adeva Andany, Bernardo; Álvarez Cartelle, Paula; Dosil Suárez, Álvaro; Fernández Albor, Víctor Manuel; Gallas Torreira, Abraham Antonio; García Pardiñas, Julián; Hernando Morata, José Ángel; Plo Casasus, Máximo; Romero Vidal, Antonio; Saborido Silva, Juan José; Sanmartín Sedes, Brais; Santamarina Ríos, Cibrán; Vázquez Regueiro, Pablo; Vázquez Sierra, Carlos; Vieites Díaz, María (Springer, 2015)
      A study of B and Bs meson decays into J/ψ η and J/ψ η′ final states is performed using a data set of proton-proton collisions at centre-of-mass energies of 7 and 8 TeV, collected by the LCHb experiment and corresponding ...
