Recent results on hadronic spectroscopy at LHCb [PDF]
EPJ Web of Conferences, 2019 The LHCb experiment is optimized to make precision measurements in the flavour sector. The large datasets collected between 2010 and 2016 allow to study the properties of heavy hadrons with unprecedented precision.

Masses of Hadrons, Tetraquarks, and Pentaquarks Through a Tsallis-Entropy Approach in the MIT Bag Model [PDF]
EntropyWe propose a new approach to describe hadrons and new forms of quark matter in the MIT bag model. The proposal is an extension that integrates a Tsallis nonextensive statistics description of quarks and gluons and is shown to capture the main features ...

Hadronic vacuum polarization in the muon g − 2: the short-distance contribution from lattice QCD
Journal of High Energy PhysicsWe present results for the short-distance window observable of the hadronic vacuum polarization contribution to the muon g – 2, computed via the time-momentum representation (TMR) in lattice QCD.

Quark Forces from Hadronic Spectroscopy [PDF]
Physical Review Letters, 2009 We consider the implications of the most general two-body quark-quark interaction Hamiltonian for the spin-flavor structure of the negative parity L=1 excited baryons. Assuming the most general two-body quark interaction Hamiltonian, we derive two correlations among the masses and mixing angles of these states, which constrain the mixing angles, and ...

X ray spectroscopy on 𝚵− atoms (J-PARC E03, E07 and future) [PDF]
EPJ Web of Conferences, 2022 X-ray spectroscopy of hadronic atoms is a powerful method to study strong interaction between hadrons and nuclei. At J-PARC, we have conducted two experiments, J-PARC E07 and E03, for hadronic atoms with a doubly strange hyperon, Ξ−, aiming at the world ...

Hadronic currents and form factors in three-body semileptonic $$\tau $$ τ decays
European Physical Journal C: Particles and Fields, 2021 Three-body semileptonic $$\tau $$ τ -decays offer a path to understand the properties of light hadronic systems and CP symmetry violations through searches for electric dipole moments.

Two Schrödinger-like Equations for hadrons [PDF]
EPJ Web of Conferences, 2022 In this talk, based on [1, 2], I argue that the holographic Schrödinger Equation of (3 +1)-dim, conformal light-front QCD and the ’t Hooft Equation of (1+1)-dim, large Nc QCD, can be complementary to each other in providing a first approximation to ...

Interactions of πK, ππK and KKπ systems at maximal isospin from lattice QCD
Journal of High Energy Physics, 2023 We study the interactions of systems of two and three nondegenerate mesons composed of pions and kaons at maximal isospin using lattice QCD, specifically π + K +, π + π + K + and K + K + π +.
