    • Forward backward asymmetries of lepton pairs in events with a large transverse momentum jet at hadron colliders 

      Águila López, Francisco del; Ametller Congost, Lluís; Talavera Sánchez, Pedro (2002-10)
      Article
      Accés obert
      We discuss forward-backward charge asymmetries for lepton-pair production in association with a large-transverse-momentum jet at hadron colliders. The lepton charge asymmetry relative to the jet direction AjFB gives a new ...

    • Hidden conformal symmetry and entropy of Schwarzschild–de Sitter spacetime 

      Guerrero Domínguez, Daniel; Talavera Sánchez, Pedro (American Physical Society (APS), 2022-12-16)
      Article
      Accés obert
      In this paper we treat two aspects of a black hole (BH) immersed in the Schwarzschild–de Sitter (SdS) spacetime. First we show that the equation of motion of a massless scalar particle near the BH horizon enjoys a hidden ...

    • Insights into Q2Qbar2 states from an effective perspective 

      Ametller Congost, Lluís; Talavera Sánchez, Pedro (American Physical Society, 2015-10-07)
      Article
      Accés obert
      We discuss the two-photon coupling of the lightest scalar meson on the basis of an extension of χPT. Using low-energy data on the pion form factor and the γγ→π+π−(π0π0) cross sections as inputs, we find Γ(σ→γγ)≅0.126  keV. ...

    • Lowest resonance in QCD from low-energy data 

      Ametller Congost, Lluís; Talavera Sánchez, Pedro (American Physical Society, 2014-05-12)
      Article
      Accés obert
      We worked out a generalization of su(2) chiral perturbation theory, including a perturbative singlet scalar field. The approach suggests that the prediction for sensible low-energy observables converge faster towards ...

    • New design of gravitational wave detectors 

      Jaen Herbera, Javier; Talavera Sánchez, Pedro (2021-05-06)
      Article
      Accés obert
      We propose a novel approach to detect gravitational waves based on a semi-rigid detector. The approach relies upon the time delay that the light takes to travel from a fixed mirror at the end of a rigid bar to a nearby ...

    • On cosmological expansion and local physics 

      Pons Ràfols, Josep Maria; Talavera Sánchez, Pedro (2021-11)
      Article
      Accés obert
      We find an exact convergence in the local dynamics described by two supposedly antagonistic approaches in modern cosmology: one starting from an expanding universe perspective such as FLRW, the other based on a local model ...
