Abstract

We discuss recent developments in electromagnetic production of kaon of a nucleon. A detailed chronological progress in this field is presented. Special attention is given for the isobar model which is not only useful for explaining experimental data, but also important in the nuclear application. Other applications, such as in the quest of "missing resonances" and in the investigation of the hadronic as well as electromagnetic baryon form factors, are also discussed. We also touch on the latest achievements in Regge models and multipole analyses of this process. The basic formalism required for numerical calculations is also thoroughly presented.

Abstract

We review the progress in current understanding of the hypernuclear production through electromagnetic interaction. The motivation behind the interest in this investigation, i.e., the hyperon-nucleon force, is briefly overviewed. Special attention is given for the kaon productions on a deuteron and 3He. We also discuss some advantages of electromagnetic production of hypernucleus compared with the hadronic one.

Abstract

The static properties of hadrons, such as their radii and other moments of the electric and magnetic distributions, can only be extracted using theoretical methods and cannot be directly measured from experiments. As a result, discrepancies between the extracted values from different precision measurements can exist. The proton charge radius, rp, which is extracted either from electron-proton (e-p) elastic scattering data or from hydrogen atom spectroscopy, seems to be no exception. The value rp = 0.84087(39) fm extracted from muonic hydrogen spectroscopy is about 4% smaller than that obtained from e-p scattering or standard hydrogen spectroscopy. The resolution of this so-called proton radius puzzle has been attempted in many different ways over the past six years. The present article reviews these attempts with a focus on the methods of extracting the radius.

Abstract

We have extracted the kaon-hyperon-nucleon coupling constant by means of a model-independent method and recent experimental data on kaon photoproduction off a nucleon. The extracted coupling constant is consistent with the SU(3) prediction as well as with the values obtained from the kaon-nucleon scattering process.

Abstract

A sophisticated machine of radiotherapy treatment process follows the complexity of the quality assurance (QA) measurement. Non-measurement QA becomes one of the solutions to reduce the medical physicists’ workload. However, this method has not been clinically established. This study compared two non-measurement methods of patient-specific quality assurance (PSQA) to find the feasible algorithm for the adaptive radiotherapy process. Monte Carlo-based (MC) PSQA used a phase space file of the medical linear accelerator (Linac) to obtain the photon energy fluence and forward projected to the isoplane. In contrast, Modified Clarkson Integration-based (MCI) used a non-uniform fluence map in the isoplane. For the modulated intensity, we used a pair of the dynamic log files of the multileaf-collimator (MLC) and then employed them in the algorithms. The dose distributions of MC and MCI methods were compared to the treatment planning system (TPS) using gamma index analysis. We found that the gamma pass rates (GPR) for MC-TPS and MCI-TPS were 99.54% and 99.57%, respectively. Further, the dose distribution in the off-axis region for the MCI method showed lesser accuracy due to the higher secondary dose contribution. The linac log file information can be used and calculated into a 2D dose distribution using both MC and MCI methods, providing high-accuracy results.
