Kaon Structure in the Nuclear Medium within the Light Front Approach
G. H. S. O. Yabusaki, J. P. B. C. de Melo, K. Tsushima +2
We study the properties of the charged kaon in symmetric nuclear matter using a Bethe-Salpeter amplitude to model the quark-anti-quark bound state, which is well constrained by pre…
Pseudoscalar current and covariance with the light-front approach
Jurandi Leãoo, J. P. B. C. de Melo
Quantum Field Theory (QFT) is used to describe the physics of particles in terms of their fundamental constituents. The Light-Front Field Theory~(LFFT), introduced by Paul Dirac in…
Covariant form factors for spin-1 particles
J. P. B. C. de Melo
Spin-1 particles, is a fundamental bound state for the two quarks, and play a crucial role in elucidating the electromagnetic properties within the realm of hadronic physics. Their…
The cosmic waltz of Coma Berenices and Latyshev 2 (Group X). Membership, phase-space structure, mass, and energy distributions
J. Olivares, N. Lodieu, V. J. S. Béjar +3
Context. Open clusters (OCs) are fundamental benchmarks where theories of star formation and stellar evolution can be tested and validated. Coma Ber and Latyshev 2 (Group X) are th…
Dynamical age of the Tucana-Horologium young stellar association
Phillip A. B. Galli, Núria Miret-Roig, Hervé Bouy +2
The Tucana-Horologium association is one of the closest young stellar groups to the Sun and despite the close proximity its age is still debated in the literature. We take advantag…
Boundary conditions in hydrodynamic simulations of isolated galaxies and their impact on the gas-loss processes
Anderson Caproni, Gustavo A. Lanfranchi, Amâncio C. S. Friaça +1
Three-dimensional hydrodynamic simulations are commonly used to study the evolution of the gaseous content in isolated galaxies, besides its connection with galactic star formation…
