Strange pentaquarks with a hidden heavy quark-antiquark pair
Sachiko Takeuchi, Alessandro Giachino, Makoto Takizawa +2
The strange pentaquarks with hidden heavy quark pair ( and ) are investigated by the coupled-channel quark cluster model. Two types of the color-octe…
Quark mass dependence of the pole
F. Gil-Domínguez, A. Giachino, R. Molina
Recently, several LQCD simulations have proven that the interaction in the isoscalar channel in scattering is attractive. This channel is naturally connected to the $T_{cc}(…
Fully charmed tetraquark production at the LHC experiments
Ilia Belov, Alessandro Giachino, Elena Santopinto
We develop the formalism for production of a fully heavy tetraquark and apply it to the calculation of cross-sections. We demonstrate that the production cross-sec…
A new subtraction scheme at NLO exploiting the privilege of kT-factorization
Alessandro Giachino, Andreas van Hameren, Grzegorz Ziarko
We present a subtraction method for the calculation of real-radiation integrals at NLO in hybrid kT-factorization. The main difference with existing methods for collinear factoriza…
Decay widths and mass spectra of single bottom baryons
H. García-Tecocoatzi, A. Giachino, A. Ramirez-Morales +3
We develop a Hamiltonian model that incorporates the spin, spin-orbit, and isospin interactions to determine the masses of the ground states of single-bottom baryons and their exci…
Strong Interaction Physics at the Luminosity Frontier with 22 GeV Electrons at Jefferson Lab
A. Accardi, P. Achenbach, D. Adhikari +441
This document presents the initial scientific case for upgrading the Continuous Electron Beam Accelerator Facility (CEBAF) at Jefferson Lab (JLab) to 22 GeV. It is the result of a…
One-loop gauge invariant amplitudes with a space-like gluon
Etienne Blanco, Alessandro Giachino, Andreas van Hameren +1
Nowadays the particle physics has entered an era where high precision calculations are required in order to compare the theoretical predictions with the experimental data. In this…
Rich structure of the hidden-charm pentaquarks near threshold regions
Alessandro Giachino, Atsushi Hosaka, Elena Santopinto +3
The recent abundant observations of pentaquarks and tetraquarks by high-energy accelerator facilities indicate the realization of the conjecture by Gell-Mann and Zweig, and by De R…

H. Garcia-Tecocoatzi, A. Giachino, J. Li +2
The total decay widths of the charmed baryons are calculated by means of the model. Our calculations consider in the final states: the charmed baryon-(vector/pseudoscalar)…

Roelof Bijker, Hugo García-Tecocoatzi, Alessandro Giachino +2
In this article, we present a complete classification of the negative parity and -wave states: 7 belonging to the flavor sextet and 7 to the flavor…
Heavy Hybrid Decays in a Constituent Gluon Model
Christian Farina, Hugo Garcia Tecocoatzi, Alessandro Giachino +2
A constituent gluon model that is informed by recent lattice field theory is developed. The model is then used to compute hybrid strong decay widths, that can be useful for the Glu…
