Symmetry Preserving Contact Interaction Approaches: An Overview of Meson and Diquark Form Factors

L. X. Gutiérrez-Guerrero, Roger José Hernández-Pinto

We present an updated overview of the symmetry preserving Contact Interaction model in hadronic physics, developed a little over a decade ago to describe the mass spectrum and inte…

Search for TeV emission from spider millisecond pulsars with HAWC

R. Alfaro, E. Anita-Rangel, M. Araya +90

Millisecond pulsars (MSPs) are observed to emit multi-wavelength radiation, from radio to GeV. Spider MSPs, which interact with their low-mass companion in close orbit (orbital per…

Unified analysis of screening masses for vector and axial-vector mesons and their diquark partners in the Contact Interaction model

L. X. Gutiérrez-Guerrero, M. A. Ramírez-Garrido, M. A. Pérez de León +1

We present a comprehensive study of the screening masses of vector and axial-vector mesons and their corresponding diquark partners within a symmetry-preserving vector-vector conta…

Search for ultra-high energy neutrons from Galactic sources with the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +357

Deflections in the propagation of charged ultra-high-energy cosmic rays (UHECRs) caused by magnetic fields make the identification of their sources challenging. On the other hand,…

The first 10years of the HAWC Gamma-Ray Observatory: science results

Anna Lia Longinotti, HAWC Collaboration

The High-Altitude Water Cherenkov (HAWC) Observatory, located on the slopes of the Sierra Negra volcano in Mexico, began operations in March 2015. Over the past decade, HAWC has en…

Spectral distortions in the decaying QCD dark matter scenario

Jorge Mastache, Raúl Henriquez-Ortiz

We study the QCD--DM scenario by analyzing the imprint of energy injection from decaying dark-sector particles on the spectral distortions (SDs) of the Cosmic Microwave Background…
