Electroweak vector boson production in joint resummation

We study the application of the joint resummation to electroweak boson production at hadron colliders. The joint resummation formalism resums both threshold and transverse momentum corrections to the transverse momentum distribution at next-to-leading logarithmic accuracy. We obtain a good description of the transverse momentum distribution of Z bosons produced at the Tevatron collider.Comment: 5 pages, 2 figures. Talk presented by A.

The resummed Higgs boson transverse momentum distribution at the LHC

We apply QCD resummation techniques to study the transverse momentum distribution of Higgs bosons produced via gluon-gluon fusion at the LHC. In particular we focus on the joint resummation formalism which resums both threshold and transverse momentum corrections simultaneously. A comparison of results obtained in the joint and the standard recoil resummation frameworks is presented.Comment: 9 pages, 1 figure, uses appolb.cls.

Revenue Management Perspectives in Small-Farm Winery Operations

This exploratory multiple case study illustrates how revenue management decisions of small-farm winery owners may contribute to business sustainability in a regulated industry through the lens of dynamic capabilities. Given small-farm winery owners focus on brand development and customer base growth to sustain long-term survival, the findings of this study highlight the connection of revenue management tenets to pricing and inventory decisions to sustain full capacity and maximize revenue. Furthermore, the results indicate that small-farm winery owners’ revenue management strategic decisions may be influenced by resource and regulatory constraints and competitors’ impact on pricing and distribution tactics

Analysis of Contextual Factors Influence on Auditors Informal Learning

In the next decade, more than 1 billion people will need reskilling as professional roles evolve. Even more importantly, the COVID-19 pandemic is forcing organizations to rethink the entire role of organizational learning in both the short- and long-term. As a consequence of this change, professionals need to be motivated to continually further their own skill sets in addition to organizational needs. The purpose of this study was to investigate the hours auditors engage in learning activities integrated into daily work tasks and factors that support engagement in learning. Further, the study provided insight into auditors’ informal learning preferences at different levels of work experience and auditors’ tendency to participate given the level of the perceived organizational learning culture

Polycomb Repressive Complex 2 Targets Murine Cytomegalovirus Chromatin for Modification and Associates with Viral Replication Centers

Regulation of viral transcription by chromatin structure has emerged as a fundamental determinant in the establishment of lytic and latent herpesvirus infections. The Polycomb group (PcG) of epigenetic repressors promotes heterochromatin formation by trimethylating histone H3 on lysine-27 (H3K27me3) and regulates development, stem cell renewal and differentiation and the cell cycle. These cellular processes are tightly coupled to the molecular switch between lytic and latent herpesvirus infections. Using chromatin immunoprecipitation analysis, we observed enrichment of H3K27me3 at the major immediate-early (MIE) locus of murine cytomegalovirus (MCMV) very early following infection of permissive fibroblasts. As lytic replication progressed, we observed a loss of H3K27me3 enrichment concomitant with the appearance of H3K4me3. However, late during infection, as viral replication centers are established, we observed a significant increase in PcG protein association with chromatin. Additionally, in co-immunofluorescence assays using confocal microscopy, we detected strong enrichments for PcG protein within the viral replication compartment, suggesting an association between viral DNA synthesis machinery and PcG proteins. Together, our results suggest a novel, dynamic interaction between PcG epigenetic repressors and MCMV genomes

Same-sign W pair production as a probe of double parton scattering at the LHC

We study the production of same-sign W boson pairs at the LHC in double parton interactions. Compared with simple factorised double parton distributions (dPDFs), we show that the recently developed dPDFs, GS09, lead to non-trivial kinematic correlations between the W bosons. A numerical study of the prospects for observing this process using same-sign dilepton signatures, including same-sign WWjj, di-boson and heavy flavour backgrounds, at 14 TeV centre-of-mass energy is then performed. It is shown that a small excess of same-sign dilepton events from double parton scattering over a background dominated by single scattering WZ(gamma*) production could be observed at the LHC.Comment: 14 pages, 8 figures.

Essential Qualifications: Accounting Faculty Selection Trends

Colleges and universities are challenged with attracting faculty with the essential qualifications to deliver accounting degree programs that meet the accounting profession’s needs. Budget constraints and accreditation standards further influence colleges and universities hiring trends, particularly in the specialized areas of tax and audit. Before the pandemic, business schools began adjusting their hiring practices to address these challenges. Furthermore, institutions were redesigning degree programs to be consistent with the implemented changes in professional certification exams. The disruptive effects of the COVID-19 pandemic on enrollment and operational budgets have exacerbated these challenges. Consequently, institutions may need to alter their recruitment strategies to contend with faculty shortages and provide a curriculum to meet the profession’s needs. This study explored what qualifications decision-makers deemed essential for recently hired accounting faculty. Further, we investigated to what extent particular academic institutional characteristics influenced the selection of an accounting faculty candidate. Finally, this study also reports on the trend in the essential qualifications preferred for new accounting faculty hires

Non-perturbative effects and the resummed Higgs transverse momentum distribution at the LHC

We investigate the form of the non-perturbative parameterization in both the impact parameter (b) space and transverse momentum (p_T) space resummation formalisms for the transverse momentum distribution of single massive bosons produced at hadron colliders. We propose to analyse data on Upsilon hadroproduction as a means of studying the non-perturbative contribution in processes with two gluons in the initial state. We also discuss the theoretical errors on the resummed Higgs transverse momentum distribution at the LHC arising from the non-perturbative contribution.Comment: 22 pages, 10 figure

Phenomenological studies in QCD resummation

We study applications of QCD soft-gluon resummations to electroweak annihilation cross sections. We focus on a formalism that allows to resum logarithmic corrections arising near partonic threshold and at small transverse momentum simultaneously.Comment: 7 pages, LaTeX, 3 figures as eps files.

The q_T spectrum of the Higgs boson at the LHC in QCD perturbation theory

We consider the transverse-momentum (q_T) distribution of Higgs bosons produced at hadron colliders. We use a formalism that uniformly treats both the small-q_T and large-q_T regions in QCD perturbation theory. At small q_T (q_T << M_H, M_H being the mass of the Higgs boson), we implement an all-order resummation of logarithmically-enhanced contributions up to next-to-next-to-leading logarithmic accuracy. At large q_T (q_T \gtap M_H), we use fixed-order perturbation theory up to next-to-leading order. The resummed and fixed-order approaches are consistently matched by avoiding double-counting in the intermediate-q_T region. In this region, the introduction of unjustified higher-order terms is avoided by imposing unitarity constraints, so that the integral of the q_T spectrum exactly reproduces the perturbative result for the total cross section up to next-to-next-to-leading order. Numerical results at the LHC are presented. These show that the main features of the q_T distribution are quite stable with respect to perturbative QCD uncertainties.Comment: 9 pages, 2 postscript figure
