Towards a unified description of hadron scattering at all energies

Autor: Stamen, Dominik, Winney, Daniel, Rodas, Arkaitz, Fernandez-Ramirez, Cesar, Mathieu, Vincent, Montana, Gloria, Pilloni, Alessandro, Szczepaniak, Adam P.

The construction of general amplitudes satisfying symmetries and $S$-matrix constraints has been the primary tool in studying the spectrum of hadrons for over half a century. In this work, we present a new parameterization, which can fulfill many exp

Studying $\pi^+\pi^-$ photoproduction beyond Pomeron exchange

Autor: Bibrzycki, Łukasz, Hammoud, Nadine, Mathieu, Vincent, Perry, Robert J., Akridge, Alex, Fernández-Ramírez, César, Montaña, Gloria, Pilloni, Alessandro, Rodas, Arkaitz, Shastry, Vanamali, Smith, Wyatt A., Winney, Daniel, Szczepaniak, Adam P.

Forward photoproduction of $\pi^+\pi^-$ pairs with invariant mass of the order of $m_\rho\sim 770$ MeV is traditionally understood to be produced via Pomeron exchange. Based on a detailed analysis of the CLAS photoproduction data, it is shown that th

Effect of the Large Magellanic Cloud on the kinematics of Milky Way satellites and virial mass estimate

Autor: Kravtsov, Andrey, Winney, Sophia

Publikováno v: The Open Journal of Astrophysics, Vol 7, June 21, 2024

We present a study illustrating the effects of the passage of a Large Magellanic Cloud (LMC) mass satellite on the distance and velocity distributions of satellites in $\Lambda+$Cold Dark Matter simulations of Milky Way (MW) sized halos. In agreement

How many vector charmonium(-like) states sit in the energy range from $4.2$ to $4.35$ GeV?

Autor: von Detten, Leon, Baru, Vadim, Hanhart, Christoph, Wang, Qian, Winney, Daniel, Zhao, Qiang

In recent years many vector charmonium(-like) states were reported by different electron-positron collider experiments above $4.2$ GeV. However, so far, there not only exists sizable tension in the parameters of those states, but there is also no con
