Workshop on QCD

Poster presentation

We propose an explanation of the inverse mass hierarchy of the low-lying nonet of the scalar mesons in the framework of the massless Nambu–Jona-Lasinio U_R(3)xU_L(3) quark model. The collective meson states are described via quark–antiquark pairs, whose condensates lead simultaneously to spontaneous breaking of chiral and flavour symmetries. It is shown that, due to flavour symmetry breaking,...

108. Development and Performance of the Real-Time Muon Reconstruction for the L0 Trigger in HL-LHC ATLAS

High Energy Particle Physics

Poster presentation

We will present a detailed performance assessment of the implemented logic and provide an in-depth discussion of the validation strategy and methodology, which has been successfully integrated into our development workflow for the muon reconstruction in the Level-0 (L0) trigger in HL-LHC. The muon trigger will be fully upgraded with a real-time reconstruction system for HL-LHC. The new logic,...

Talk

We show that the 𝑋_17 vector boson, introduced to explain the 8Be anomalous decay, could play a role in the muon’s (electron’s) anomalous magnetic moment and the muonic Lamb shift anomaly. We compute an upper bound on the couplings of 𝑋_17 to leptons and nucleons, analyzing these anomalies. We further constrain the possible kinetic mixing with the 𝑈(1)_𝑌 boson of the Standard Model by using...

44. Mechanisms of Matter Generation in the Early Universe: Leptogenesis and Baryogenesis

Mr Bakhtiyar Iskakov (Farabi Universuty)

Cosmology, Astrophysics, Gravity, Mathematical Physics

Poster presentation

Introduction
One of the most profound questions in modern physics is why the Universe is dominated by matter, with virtually no primordial antimatter observed today. According to the Standard Model of cosmology, the early Universe should have produced matter and antimatter in equal quantities during the Big Bang. However, the observable Universe shows a clear asymmetry: matter prevails. This...
