Remarks on Topological SUSY in sixdimensional TQFTs

We establish the existence of the topological vector supersymmetry in the six dimensional topological field theory for two-form fields introduced by Baulieu and West. We investigate the relation of these symmetries to the twist operation for the (2,0) supersymmetry and comment on their resemblance to the analogous symmetries in topological Yang-Mills theory.Comment: 12 pages, to be published in JHEP 11(1999)03

Religious Behavior of Indonesian Muslims as Responses to the Covid-19 Pandemic

Covid-19 has become a world pandemic, and Indonesia is among the worse cases. Problems that arise are faced by all parties, including religious elites as well as laypeople. This study was conducted to describe how Muslims in Indonesia responded to and tried to cope with the Covid-19 pandemic. The study uses descriptive qualitative methods to collect data by observation, in-depth interview by phone, and online searching documents. From the research conducted, Islamic mass organizations have a relatively similar opinion that limits religious activities supported by various religious arguments. As for laypeople’s behavior, most are the same as mass organizations and Islamic leaders; very few have different behaviors. In anticipation of the virus spreading, most of them restricted religious activities in full by closing down the mosque and stopping public prayers. Few remained active as before the Covid-19 pandemic

Planar Two-Loop Five-Parton Amplitudes from Numerical Unitarity

We compute a complete set of independent leading-color two-loop five-parton amplitudes in QCD. These constitute a fundamental ingredient for the next-to-next-to-leading order QCD corrections to three-jet production at hadron colliders. We show how to consistently consider helicity amplitudes with external fermions in dimensional regularization, allowing the application of a numerical variant of the unitarity approach. Amplitudes are computed by exploiting a decomposition of the integrand into master and surface terms that is independent of the parton type. Master integral coefficients are numerically computed in either finite-field or floating-point arithmetic and combined with known analytic master integrals. We recompute two-loop leading-color four-parton amplitudes as a check of our implementation. Results are presented for all independent four- and five-parton processes including contributions with massless closed fermion loops.Comment: v3: corrected wrong signs for five-gluon $N_f^2$ amplitudes with vanishing tree

Profile Analysis of Critical Thinking Ability of Science Education Study Program Students

In order to produce superior human resources according to the demands of 21st- century competence and be resilient in facing global challenges in the era of society 5.0, the ability to think critically must be mastered. Critical thinking is a key competency needed by university graduates and most universities have determined this ability as one of the attributes that must be supplied to their graduates. This study aims to analyze the profile of critical thinking skills of Science Education Study Program students. The subjects in this study were 147 students of the Science Education Study Program, Faculty of Tarbiyah and Teacher Training UINSA, class of 2020, 2021, and 2022, totaling 147 students. Critical thinking skills are measured using a critical thinking question instrument consisting of 10 essay questions with 10 indicators of critical thinking skills. The questions tested are questions that have been revised and declared valid by expert validators. The results of the critical thinking ability test are analyzed descriptively to see the category of critical thinking skills in students and each indicator. This study revealed that the critical thinking ability profile of the students of the Science Education Study Program was dominated by the low category, which was 32.3%. Critical thinking indicators that get high categories are indicators of analyzing conclusions, logic classes, and definitions; obtain medium categories on indicators of problem formulation, reasoning ability, and short intervals between observation and report; Getting a low category on indicators assesses the correctness of assumptions, makes and considers decisions, as well as formulates alternative solutions

An AKARI Search for Intracluster Dust of Globular Clusters

We report the observations of 12 globular clusters with the AKARI/FIS. Our goal is to search for emission from the cold dust within clusters. We detect diffuse emissions toward NGC 6402 and 2808, but the IRAS 100-micron maps show the presence of strong background radiation. They are likely emitted from the galactic cirrus, while we cannot rule out the possible association of a bump of emission with the cluster in the case of NGC 6402. We also detect 28 point-like sources mainly in the WIDE-S images (90 micron). At least several of them are not associated with the clusters but background galaxies based on some external catalogs. We present the SEDs by combining the near-and-mid infrared data obtained with the IRC if possible. The SEDs suggest that most of the point sources are background galaxies. We find one candidate of the intracluster dust which has no mid-infrared counterpart unlike the other point-like sources, although some features such as its point-like appearance should be explained before we conclude its intracluster origin. For most of the other clusters, we have confirmed the lack of the intracluster dust. We evaluate upper limits of the intracluster dust mass to be between 1.0E-05 and 1.0E-03 solar mass depending on the dust temperature. The lifetime of the intracluster dust inferred from the upper limits is shorter than 5 Myr (T=70K) or 50 Myr (35K). Such short lifetime indicates some mechanism(s) are at work to remove the intracluster dust. We also discuss its impact on the chemical evolution of globular clusters.Comment: Accepted for publication in PASJ AKARI special issue. 14 pages, 11 figure
