1555. Lattice QCD results for doubly heavy tetraquarks

Nuclear Physics / Physique nucléaire (DNP-DPN)

Invited Speaker / Conférencier invité

Several exotic hadrons have been discovered experimentally in recent years, some of which appear to be four-quark objects called tetraquarks. Our theoretical study uses lattice QCD to investigate the possibility of a tetraquark containing two light quarks (up, down or strange) and two bottom anti-quarks. Our results indicate a significant binding in two cases, with each tetraquark state well...

1827. New Perspectives on the Charged Pion Form Factor

We are about to enter a revolutionary new period in our understanding of the
charged pion form factor, $F_{\pi}$. As the lightest meson, it is the particle
responsible for the long-range character of the $N-N$ interaction that binds
the atomic nucleus. Furthermore, if QCD were chirally symmetric, the pion
would be massless. But chiral symmetry is dynamically broken by...

1830. First Physics Results from the GlueX Experiment

Nuclear Physics / Physique nucléaire (DNP-DPN)

CLOSED - Oral (Non-Student) / orale (non-étudiant)

The goal of the GlueX experiment is to carry out a definitive mapping of states in the light meson sector. The primary search is focused on exotic hybrid mesons as evidence of gluonic excitations, in an effort to understand the phenomenon of confinement in Quantum Chromo Dynamics. The experiment, housed in the Hall-D facility at Jefferson Lab, employs linearly polarized photons in the 8-9 GeV...

1838. $\pi^+$ Electroproduction at High $-t$

CLOSED - Oral (Student, In Competition) / Orale (Étudiant(e), inscrit à la compétition)

Measurements of exclusive meson production are a useful tool in the study of
hadronic structure. In particular, one can discern the relevant degrees of
freedom at different scales through these studies. In the transition region
between low momentum transfer (where description of hadronic degrees of freedom
in terms of effective hadronic Lagrangians is valid) and high momentum transfer
(where...

1882. The Nuclear Delta Force in Quadrupole Deformed Nuclei

When modelling excited states of deformed nuclei, nucleons can be taken collectively as a rotor, significantly simplifying the system. However, in order to take into account single-particle effects it is important to properly model the valence nucleons, especially those occupying large angular momenta orbitals near the Fermi level. For that purpose a model has been developed in which two...
