The article explores the role of pseudoscalar mesons in understanding the origin of mass in the Standard Model (SM) of particle physics. It highlights that while the Higgs boson contributes only about 1-2% of the visible mass, the remaining 98% is attributed to strong interactions, specifically quantum chromodynamics (QCD). The study focuses on the properties of pseudoscalar mesons, such as distribution amplitudes, form factors, and wave functions, to gain insights into the dynamics of mass generation. The authors use continuum Schwinger function methods to analyze these properties and their implications for experimental efforts. They emphasize the importance of pseudoscalar mesons in elucidating the interplay between emergent hadron mass (EHM) and Higgs boson (HB) couplings, which are crucial for understanding the mass of protons, pions, and kaons. The article also discusses the connection between pseudoscalar mesons and the hadron scale, a key concept in QCD, and presents predictions for various pseudoscalar meson properties, including their distribution amplitudes and parton distributions.The article explores the role of pseudoscalar mesons in understanding the origin of mass in the Standard Model (SM) of particle physics.
