Signature of the +jet and dijet production mediated by an excited quark with QCD next-to-leading order accuracy at the LHC
We present a detailed study of the production and decay of the excited quark
at the QCD next-to-leading order (NLO) level at the Large Hadron Collider,
using the narrow width approximation and helicity amplitudes method. We find
that the QCD NLO corrections can tighten the constraints on the model
parameters and reduce the scale dependencies of the total cross sections. We
discuss the signals of the excited quark production with decay mode
and , and present several
important kinematic distributions. Moreover, we give the upper limits of the
excited quark excluded mass range and the allowed parameter space for the
coupling constants and the excited quark mass.Comment: 20 pages, 13 figures; version published in PR
Threshold resummation for the production of a color sextet (antitriplet) scalar at the LHC
We investigate threshold resummation effects in the production of a color
sextet (antitriplet) scalar at next-to-next-to-leading logarithmic (NNLL) order
at the LHC in the frame of soft-collinear effective theory. We show the total
cross section and the rapidity distribution with NLO+NNLL accuracy, and we
compare them with the NLO results. Besides, we use recent dijet data at the LHC
to give the constraints on the couplings between the colored scalars and
quarks.Comment: 21 pages,9 figures,3 tables; Version published in EPJ
Inclusiveness Matters: A Large-Scale Analysis of User Feedback
In an era of rapidly expanding software usage, catering to the diverse needs
of users from various backgrounds has become a critical challenge.
Inclusiveness, representing a core human value, is frequently overlooked during
software development, leading to user dissatisfaction. Users often engage in
discourse on online platforms where they indicate their concerns. In this
study, we leverage user feedback from three popular online sources, Reddit,
Google Play Store, and Twitter, for 50 of the most popular apps in the world to
reveal the inclusiveness-related concerns from end users. Using a
Socio-Technical Grounded Theory approach, we analyzed 23,107 posts across the
three sources and identified 1,211 inclusiveness related posts. We organize our
empirical results in a taxonomy for inclusiveness comprising 6 major
categories: Fairness, Technology, Privacy, Demography, Usability, and Other
Human Values. To explore automated support to identifying inclusiveness-related
posts, we experimented with five state-of-the-art pre-trained large language
models (LLMs) and found that these models' effectiveness is high and yet varied
depending on the data source. GPT-2 performed best on Reddit, BERT on the
Google Play Store, and BART on Twitter. Our study provides an in-depth view of
inclusiveness-related user feedback from most popular apps and online sources.
We provide implications and recommendations that can be used to bridge the gap
between user expectations and software so that software developers can resonate
with the varied and evolving needs of the wide spectrum of users
Leveraging Diversity in Software Engineering Education through Community Engaged Learning and a Supportive Network
While a lack of diversity is a longstanding problem in computer science and
engineering, universities and organizations continue to look for solutions to
this issue. Among the first of its kind, we launched INSPIRE: STEM for Social
Impact, a program at the University of Victoria, Canada, aimed to motivate and
empower students from underrepresented groups in computer science and
engineering to develop digital solutions for society impactful projects by
engaging in experiential learning projects with identified community-partners.
The twenty-four students in the program came from diverse backgrounds in terms
of academic areas of study, genders, ethnicities, and levels of technical and
educational experience. Working with six community partners, these students
spent four months learning and developing solutions for a societal and/or
environmental problem with potential for local and global impacts. Our
experiences indicate that working in a diverse team with real clients on
solving pressing issues produces a sense of competence, relatedness, and
autonomy which are the basis of self-determination theory. Due to the unique
structure of this program, the three principles of self-determination theory
emerged through different experiences, ultimately motivating the students to
build a network of like-minded people. The importance of such a network is
profound in empowering students to succeed and, in retrospect, remain in
software engineering fields. We address the diversity problem by providing
diverse, underrepresented students with a safe and like-minded environment
where they can learn and realize their full potential. Hence, in this paper, we
describe the program design, experiences, and lessons learned from this
approach. We also provide recommendations for universities and organizations
that may want to adapt our approach
