Searching for diboson resonances in the boosted all-hadronic final state at s = 13 TeV with CMS

This article summarizes three searches for diboson resonances in the all-hadronic final state using data collected at a center-of-mass energy of [Formula: see text] = 13 TeV with the CMS experiment at the CERN LHC. The boson decay products are contained in one large-radius jet, resulting in dijet final states which are resolved using jet substructure techniques. The analyses presented use 2.3 fb[Formula: see text], 35.9 fb[Formula: see text] and 77.3 fb[Formula: see text] of data collected between 2015 and 2017. These include the first search for diboson resonances in data collected at a 13 TeV collision energy, the introduction of a new algorithm to tag vector bosons in the context of analyzing the data collected in 2016, and the development of a novel multidimensional fit improving on the sensitivity of the previous search method with up to 30%. The results presented here are the most sensitive to date of all diboson resonance searches in the dijet final state. An emphasis on improvements in technique for vector boson tagging is made.

How to keep brand fan page followers? The lens of person-environment fit theory

Purpose Companies create brand fan pages (BFPs) on social media platforms to broadcast product information, increase brand awareness and engage customers. A common challenge facing BFPs is how to attract and retain followers effectively. Through the lens of the theory of person–environment fit (TPEF), the purpose of this paper is to develop and validate a theoretical model to explain the role of multidimensional fit perceptions in cultivating BFP users’ continued following intention. Design/methodology/approach Data collected from 193 active followers of BFPs on Sina Weibo, the most prevalent social media platform in China, were used to test the proposed model. The partial least squares method was employed to assess the relationships in the model. Findings The findings reveal that users will continue to follow the BFP if their needs align with what the BFP provides, and if they perceive their values and characteristics to match those of the brand and fellow followers. Originality/value This study is among the first to extend the research context of the TPEF from organizational behaviors to examining how perceived fit influences users’ continued intention to follow in the social media context. In addition to the theoretical contributions, the findings of this study have important implications for practitioners who undertake social media management or user behavior analysis.
