Abstract We study the $$J/\psi \rightarrow \phi K \bar{K}$$ J / ψ → ϕ K K ¯ decay, looking for differences in the production rates of $$K^+ K^-$$ K + K - or $$K^0 \bar{K}^0$$ K 0 K ¯ 0 in the region of 1700–1800 MeV, where two resonances appe

Abstract We revisit the thermal production and annihilation of magnetic monopoles and their relic abundance in order to gain a deeper physical interpretation on the monopole phenomenology predicted from the Baines et al.’s effective field theory, r

We reassess the decay of the J/ψ into an ω,ϕ,K⁎0 and one of the f0(1370), f0(1710), f2(1270), f2′(1525), K0⁎(1430) and K2⁎(1430) resonances. We benefit from previous works that considered this reaction as a J/ψ decay into three vector mes

Motivated by the recently observation of the tetraquark Tcc+ state, in this work I revisit the Heavy-Meson Effective Theory to perform a simplified field-theoretical study of possible deuteron-like D(⁎)D(⁎),B¯(⁎)B¯(⁎) and D(⁎)B¯(⁎) mol

Abstract We predict that triangle singularities of hadron spectroscopy can be strongly affected in heavy ion collisions. To do it we examine various effects on the singularity-inducing triangle loop of finite temperature in the terminal hadron phase.

We study the $J/\psi \to \phi K \bar K$ decay, looking for differences in the production rates of $K^+ K^-$ or $K^0 \bar K^0$ in the region of 1700-1800 MeV, where two resonances appear dynamically generated from the vector-vector interaction. Two re

In this work we investigate the hadronic effects on the ${X}_{J=0,1}(2900)$ states in heavy-ion collisions. We make use of effective Lagrangians to estimate the cross sections and their thermal averages of the processes ${X}_{J}\ensuremath{\pi}\ensur

In this work, we present an updated study about the interactions of quarkonia with surrounding hadronic medium. The meson-meson interactions are described with a chiral effective Lagrangian within the framework of unitarized coupled channel amplitude
