Inclusive B-decay spectra and IR renormalons. [PDF]
, 2010 I illustrate the role of infrared renormalons in computing inclusive B-decay spectra. I explain the relation between the leading ambiguity in the definition of Sudakov form factor exp(N /M) and that of the pole mass, and show how these ambiguities ...

, 2014 Gamification marks a major change to everyday life. It describes the permeation of economic, political, and social contexts by game-elements such as awards, rule structures, and interfaces that are inspired by video games.

Investigation of the meson-meson interaction
Physical Review C, 2022 In the framework of the quark delocalization color screening model, we investigate the meson-meson interaction in the fully light four-quark system . The calculation of the effective potentials of all the $S-$wave states shows that for most states the interaction between two vector mesons is attractive; the one between a pseudoscalar meson and a vector

Vector meson dominance and the ρ meson [PDF]
Physical Review D, 1999 We discuss the properties of vector mesons, in particular the rho^0, in the context of the Hidden Local Symmetry (HLS) model. This provides a unified framework to study several aspects of the low energy QCD sector. Firstly, we show that in the HLS model the physical photon is massless, without requiring off field diagonalization.

Measurement of the Bc +meson lifetime using Bc +→J/ψμ+νμX decays [PDF]
, 2014 The lifetime of the B+ c meson is measured using semileptonic decays having a J/ψ meson and a muon in the final state. The data, corresponding to an integrated luminosity of 2 fb-1, are collected by the LHCb detector in pp collisions at a centre-of-mass ...

A study of the vector meson ψ(4040) [PDF]
, 2019 We investigate the well-known vector state ψ(4040) in the frame-work of a quantum field theoretical model. In particular, we study its spectral function and search for the pole(s) in the complex plane. Quite interestingly, the spectral function has a non-

Meson exchange model for pseudoscalar meson-meson scattering [PDF]
Nuclear Physics A, 1990 A dynamical model for pseudoscalar-pseudoscalar meson scattering based on meson exchange, suitable for use in a variety of low- and intermediate-energy mesonic interactions, has been constructed and applied to ππ and kπ scattering with good quantitative results.

f_{0}(1370) Controversy from Dispersive Meson-Meson Scattering Data Analyses. [PDF]
, 2023 We establish the existence of the long-debated f_{0}(1370) resonance in the dispersive analyses of meson-meson scattering data. For this, we present a novel approach using forward dispersion relations, valid for generic inelastic resonances.
