The Y(4230) as a D1D molecule [PDF]
EPJ Web of Conferences. We show that the currently available data are consistent with Y(4230) being a D1D¯ hadronic molecule. By a simultaneous fit to data from e+e− → D0D*−π+, J/ψπ+π−, J/ψK+ K−, hcπ+π−, J/ψη, χc0ω, χc1(3872)γ and µ+µ−, we demonstrate that this single state ...

Nuclear Attenuation of high energy two-hadron system in the string model [PDF]
, 2006 Nuclear attenuation of the two-hadron system is considered in the string model. The two-scale model and its improved version with two different choices of constituent formation time and sets of parameters obtained earlier for the single hadron ...

Phenomenology of near-threshold states: a practical parametrisation for the line shapes
EPJ Web of Conferences, 2017 In the last decade many states in the spectrum of charmonium and bottomonium have been observed experimentally above the lowest open-flavour threshold.

Generating a resonance-like structure in the reaction $$B_c\rightarrow B_s \pi \pi $$ B c → B s π π
European Physical Journal C: Particles and Fields, 2017 We investigate the process $$B_c^+\rightarrow B_s^0\pi ^+\pi ^0$$ B c + → B s 0 π + π 0 via $$B\bar{K}^*$$ B K ¯ ∗ rescattering. The kinematic conditions for triangle singularities are perfectly satisfied in the rescattering diagrams.

Lattice QCD and Baryon-Baryon Interactions: HAL QCD Method
Frontiers in Physics, 2020 In this article, we review the HAL QCD method to investigate baryon-baryon interactions, such as nuclear forces in lattice QCD. We first explain our strategy in detail to investigate baryon-baryon interactions by defining potentials in field theories ...

Hadron Mass Effects in Power Corrections to Event Shapes [PDF]
, 2013 We study the effect of hadron masses on the leading power correction of dijet event-shape distributions. We define the transverse velocity operator, that describes the effects of hadron masses.

Erratum to: The branching ratio $$\omega \rightarrow \pi ^+\pi ^-$$ ω→π+π- revisited
European Physical Journal C: Particles and Fields, 2018 The use of the official form factor data changes some of the results, as we report in this erratum.

Emergent geometry and duality in the carbon nucleus
Nature Communications, 2023 The carbon atom provides the backbone for the complex organic chemistry composing the building blocks of life. The physics of the carbon nucleus in its predominant isotope, 12C, is similarly full of multifaceted complexity.

High Pt hadron-hadron correlations
, 2004 We propose the formulation of a dihadron fragmentation function in terms of parton matrix elements. Under the collinear factorization approximation and facilitated by the cut-vertex technique, the two hadron inclusive cross section at leading order (LO ...
