Mapping The Toronto Theatre Blogosphere

From online reviews, to live tweeting during a performance, to “liking” a production on Facebook, the blogosphere is transforming how we talk about theatre. Theatre criticism in the digital world is now a “team sport,” where audience members and artists play alongside professional critics (Fricker 49). This shift holds much potential: online critical discourse can help us develop a more diverse and inclusive picture of theatre reception and theatre-going cultures than print reviews, and expand the historical documentation of performance, which, as a vanishing art form, leaves very few traces of itself. However, the limited research in this area has yet to fully understand the role of the blogosphere in theatre ecology or how to archive the criticism found there (Collins ; Poll ; Radosavljevic). “Mapping the Toronto Theatre Blogosphere” is a new research project bringing together Dramatic Art and Computer Science students. It attempts to answer two key questions: how is the blogosphere changing how we talk about theatre, and how can we preserve the critical discourse occurring there? To answer the first question, we tracked and archived the online critical response (blog reviews, online publications, tweets, and Facebook posts) to a representative sample from the fall 2016 Toronto theatre season. Our resulting dataset was examined using a content analysis approach in order to identify which productions generated the most critical response (posts) online, the demographics of the posters (including age, gender, occupation, and ethnicity), and the purpose of the posts (including commentary on the production, socio-political commentary, endorsements, and check-ins). To answer the second question, our CS team member is developing an open-access website to archive the materials collected, which the public will be invited to use and contribute to once it is launched. Our preliminary findings suggest that the blogosphere is changing how we talk about theatre in three key ways: it is providing more coverage to new plays and plays about political or controversial subject matter; it is increasing and diversifying the participants in critical discourse, allowing women and people of colour more access into the conversations; and it is connecting discussions about theatre to other topics such as political issues and identity. Our UWill Discover presentation will summarize our findings about the Toronto theatre blogosphere and include an interactive demonstration of our database

Search for Higgs boson pair production in the gamma gamma b(b)over-bar final state in pp collisions at root s=13 TeV

A search is presented for the production of a pair of Higgs bosons, where one decays into two photons and the other one into a bottom quark-antiquark pair. The analysis is performed using proton-proton collision data at root s = 13 TeV recorded in 2016 by the CMS detector at the LHC, corresponding to an integrated luminosity of 35.9 fb(-1) . The results are in agreement with standard model (SM) predictions. In a search for resonant production, upper limits are set on the cross section for new spin-0 or spin-2 particles. For the SM-like nonresonant production hypothesis, the data exclude a product of cross section and branching fraction larger than 2.0 fb at 95% confidence level (CL), corresponding to about 24 times the SM prediction. Values of the effective Higgs boson self-coupling K X are constrained to be within the range -11 < K-lambda < 17 at 95% CL, assuming all other Higgs boson couplings are at their SM value. The constraints on K-lambda, are the most restrictive to date. (C) 2018 The Author(s). Published by Elsevier B.V.Peer reviewe

Measurement of nuclear modification factors of ϒ(1S), ϒ(2S), and ϒ(3S) mesons in PbPb collisions at √sNN = 5.02 TeV

The cross sections for ϒ(1S), ϒ(2S), and ϒ(3S) production in lead–lead (PbPb) and proton–proton (pp) collisions at √sNN = 5.02 TeV have been measured using the CMS detector at the LHC. The nuclear modification factors, RAA, derived from the PbPb-to-pp ratio of yields for each state, are studied as functions of meson rapidity and transverse momentum, as well as PbPb collision centrality. The yields of all three states are found to be significantly suppressed, and compatible with a sequential ordering of the suppression, RAA(ϒ(1S)) > RAA(ϒ(2S)) > RAA(ϒ(3S)). The suppression of ϒ(1S) is larger than that seen at √sNN = 2.76 TeV, although the two are compatible within uncertainties. The upper limit on the RAA of ϒ(3S) integrated over pT, rapidity and centrality is 0.096 at 95% confidence level, which is the strongest suppression observed for a quarkonium state in heavy ion collisions to date

Search for excited leptons in final states in proton-proton collisions at root s=13 TeV

A search is presented for excited electrons and muons in ℓℓγ final states at the LHC. The search is based on a data sample corresponding to an integrated luminosity of 35.9 fb−1 of proton-proton collisions at a center-of-mass energy of 13 TeV, collected with the CMS detector in 2016. This is the first search for excited leptons at s√ = 13 TeV. The observation is consistent with the standard model background prediction, and the most stringent exclusion limits to date are set on the excited lepton mass and the compositeness scale, at 95% confidence level. Excited electrons and muons are excluded for masses below 3.9 and 3.8 TeV, respectively, under the assumption that the excited lepton mass equals the compositeness scale. The best observed limit on the compositeness scale is obtained with an excited lepton mass of around 1.0 TeV, excluding values below 25 TeV for both excited electrons and muons
