Analysis

This paper proposes a novel approach to understanding hadron mass spectra by applying open string theory. The key contribution is the consistent fitting of both meson and baryon spectra using a single Hagedorn temperature, aligning with lattice-QCD results. The implication of diquarks in the baryon sector further strengthens the connection to Regge phenomenology and offers insights into quark deconfinement.
Reference

The consistent value for the Hagedorn temperature, $T_{ m H} \simeq 0.34\, ext{GeV}$, for both mesons and baryons.

Analysis

This paper reviews the application of QCD sum rules to study baryoniums (hexaquark candidates) and their constituents, baryons. It's relevant because of recent experimental progress in finding near-threshold $p\bar{p}$ bound states and the ongoing search for exotic hadrons. The paper provides a comprehensive review of the method and compares theoretical predictions with experimental data.
Reference

Analysis

This paper proposes using dilepton emission rates (DER) as a novel probe to identify the QCD critical point in heavy-ion collisions. The authors utilize an extended Polyakov-quark-meson model to simulate dilepton production and chiral transition. The study suggests that DER fluctuations are more sensitive to the critical point's location compared to baryon number fluctuations, making it a potentially valuable experimental observable. The paper also acknowledges the current limitations in experimental data and proposes a method to analyze the baseline-subtracted DER.
Reference

The DER fluctuations are found to be more drastic in the critical region and more sensitive to the relative location of the critical point.

ArXiv

Analysis

This paper investigates the internal structure of observed single-bottom strange baryons (Ξb and Ξb') by studying their strong decay properties using the quark pair creation model and comparing with the chiral quark model.

Empirical Law for Galaxy Rotation Curves

Published:Dec 28, 2025 17:16
1 min read
ArXiv

Analysis

This paper proposes an alternative explanation for flat galaxy rotation curves, which are typically attributed to dark matter. Instead of dark matter, it introduces an empirical law where spacetime stores additional energy due to baryonic matter's distortion. The model successfully reproduces observed rotation curves using only baryonic mass profiles and a single parameter, suggesting a connection between dark matter and the baryonic gravitational potential. This challenges the standard dark matter paradigm and offers a new perspective on galaxy dynamics.
Reference

The model reproduced quite well both the inner rise and outer flat regions of the observed rotation curves using the observed baryonic mass profiles only.
