The Joint Physics Analysis Center is a collaboration between theorists and experimentalists working in hadronic physics. In order to facilitate the exchange of information between the different actors in hadron spectroscopy, we created an interactive website. In this note, I summarize the first projects available on the website.

New analysis of ηπ tensor resonances measured at the COMPASS experiment
We present a new amplitude analysis of the eta pi D-wave in the reaction pi(-) p -> eta pi(-) p measured by COMPASS. Employing an analytical model based on the principles of the relativistic S-m ...
The Joint Physics Analysis Center: Recent results
We review some of the recent achievements of the Joint Physics Analysis Center, a theoretical collaboration with ties to experimental collaborations, that aims to provide amplitudes suitable for the
Modeling new XYZ states at JPAC
The observation of the unexpected XYZP resonances has challenged the usual heavy quarkonium framework. One of the most studied exotic states, the X(3872), happens to be copiously produced in
Vector Meson Photoproduction with a Linearly Polarized Beam
We propose a model based on Reggae theory to describe photoproduction of light vector mesons. We fit the SLAC data and make predictions for the energy and momentum-transfer dependence of the
Global analysis of charge exchange meson production at high energies
Many experiments that are conducted to study the hadron spectrum rely on peripheral resonance production. Hereby, the rapidity gap allows the process to be viewed as an independent fragmentation of
On the η and η′ photoproduction beam asymmetry at high energies
Abstract We show that, in the Regge limit, beam asymmetries in η and η ′ photoproduction are sensitive to hidden strangeness components. Under reasonable assumptions about the couplings we estimate
Structure of pion photoproduction amplitudes
We derive and apply the finite energy sum rules to pion photoproduction. We evaluate the low energy part of the sum rules using several state-of-the-art models. We show how the differences in the low
Amplitude analysis and the nature of the Zc(3900)
Abstract The microscopic nature of the XYZ states remains an unsettled topic. We show how a thorough amplitude analysis of the data can help constraining models of these states. Specifically, we
Moments of angular distribution and beam asymmetries in ηπ0 photoproduction at GlueX
In the search for exotic mesons, the GlueX collaboration will soon extract moments of the $\eta\pi^0$ angular distribution. In the perspective of these results, we generalize the formalism of moment
Studying the P c ( 4450 ) resonance in J / ψ photoproduction off protons
A resonancelike structure, the ${P}_{c}(4450)$, has recently been observed in the $J/\ensuremath{\psi}p$ spectrum by the LHCb Collaboration. We discuss the feasibility of detecting this structure in

Understanding the nature of Λ ( 1405 ) through Regge physics
It appears that there are two resonances with $J^P= 1/2^-$ quantum numbers in the energy region near the $$\Lambda(1405)$$ hyperon. The nature of these states is a topic of current debate. To provide
Toward complete pion nucleon amplitudes
We compare the low-energy partial-wave analyses of $\ensuremath{\pi}N$ scattering with high-energy data via finite-energy sum rules. We construct a new set of amplitudes by matching the imaginary
Physics opportunities with the 12 GeV upgrade at Jefferson Lab
We summarize the scientific opportunities for utilization of the upgraded 12GeV Continuous Electron Beam Accelerator Facility (CEBAF) and associated experimental equipment at Jefferson Lab. This is
Application of the Veneziano model to the analysis of three pion charmonium decays
In this study, we adapt the Veneziano model to the analysis of vector charmonium decays. Starting from a set of covariant Veneziano terms we show how to construct partial waves amplitudes that
Relativistic dispersion relation approach to photomeson production
Relativistic dispersion relations for photomeson production, analogous to the pion-nucleon scattering dispersion relations, are formulated without proof. The assumption that the 33 resonance
Measurement of the slope parameter for the η → 3π0 decay in the pp → ppη reaction
The CELSIUS-WASA setup is used to measure the 3π0 decay of η mesons produced in pp interactions with beam kinetic energies of 1.36 and 1.45 GeV. The efficiency-corrected Dalitz plot and density
Neutral pion photoproduction in a Regge model
The reaction $$\gamma p \to \pi^0 p$$ is investigated in the energy range above the resonance region. The amplitudes include the leading Regge singularities in the cross-channel and correctly
The COMPASS experiment at CERN
The COMPASS Collaboration brings together about 220 physicists from 27 institutes from Europe, Russia, Japan and India. The goal is to study the structure and spectroscopy of hadrons by a series of
η→3π at two loops in Chiral Perturbation Theory
We calculate the decay η→3π at next-to-next-to-leading order or order p6 in Chiral Perturbation Theory. The corrections are somewhat larger than was indicated by dispersive estimates. We present

The series of workshops on New Partial-Wave Analysis Tools for Next-Generation Hadron Spectroscopy Experiments was initiated with the ATHOS 2012 meeting, which took place in Camogli, Italy, June
