Masses of Hadrons, Tetraquarks, and Pentaquarks Through a Tsallis-Entropy Approach in the MIT Bag Model [PDF]

Entropy
We 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 ...

Strong interaction studies with kaonic atoms [PDF]

EPJ Web of Conferences, 2016
The strong interaction of antikaons (K−) with nucleons and nuclei in the low-energy regime represents an active research field connected intrinsically with few-body physics.

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.

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.

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 +.

Tau and charm decays

Comptes Rendus. Physique, 2020
A summary of recent precise results in tau and charm physics is presented. Topics include leptonic and hadronic tau decays, lepton flavour and lepton number violation, charm mixing and $\mathit{CP}$ violation, leptonic and semileptonic charm decays, rare

Lattice QCD spectroscopy for hadronic CP violation

Physics Letters B, 2017
The interpretation of nuclear electric dipole moment (EDM) experiments is clouded by large theoretical uncertainties associated with nonperturbative matrix elements.

Three-particle Lellouch-Lüscher formalism in moving frames

Journal of High Energy Physics, 2023
A manifestly relativistic-invariant Lellouch-Lüscher formalism for the decays into three identical particles with no two-to-three transitions is proposed.
