IRR: Grounded in history: Spring 2022, issue 26

This issue in particular has a heavy focus on history. We seek not to rewrite history but to redefine it. Our emerging scholars offer critical analysis on myths, misconceptions, and misinformation. From articles on the Italian mafia, the role of agriculture in the Middle East, to the TRIPS waiver, we use history as a lesson and as a framework to guide the future of diplomacy. At the same time that we’ve engaged with global history, the International Relations Review also has sought to shift our own trajectory. The journal has historically published a print edition every year, but in the 2021 - 2022 academic year, we’ve increased both the quality and quantity of our content. With a team of more than 100 students, the International Relations Review pushes new frontiers with a podcast, blog, and journal

Search for dark mesons decaying to top and bottom quarks in proton-proton collisions at √s = 13 TeV with the ATLAS detector

A search for dark mesons originating from strongly-coupled, SU(2) dark favor symmetry conserving models and decaying gaugephobically to pure Standard Model final states containing top and bottom quarks is presented. The search targets fully hadronic final states and final states with exactly one electron or muon and multiple jets. The analyzed data sample corresponds to an integrated luminosity of 140 fb−1 of proton-proton collisions collected at √s = 13 TeV with the ATLAS detector at the Large Hadron Collider. No significant excess over the Standard Model background expectation is observed and the results are used to set the first direct constraints on this type of model. The two-dimensional signal space of dark pion masses mπD and dark rho-meson masses mρD is scanned. For mπD /mρD = 0.45, dark pions with masses mπD < 940 GeV are excluded at the 95% CL, while for mπD /mρD = 0.25 masses mπD < 740 GeV are excluded

Combination of searches for Higgs boson decays into a photon and a massless dark photon using pp collisions at √s = 13 TeV with the ATLAS detector

A combination of searches for Higgs boson decays into a visible photon and a massless dark photon (H → γγd) is presented using 139 fb−1 of proton-proton collision data at a centre-of-mass energy of √s = 13 TeV recorded by the ATLAS detector at the Large Hadron Collider. The observed (expected) 95% confidence level upper limit on the Standard Model Higgs boson decay branching ratio is determined to be B(H → γγd) < 1.3% (1.5)%. The search is also sensitive to higher-mass Higgs bosons decaying into the same final state. The observed (expected) 95% confidence level limit on the cross-section times branching ratio ranges from 16 fb (20 fb) for mH = 400 GeV to 1.0 fb (1.5 fb) for mH = 3 TeV. Results are also interpreted in the context of a minimal simplified model

IRR: Redefining resistance: Fall 2021, issue 25

Since 2009, the International Relations Review has contributed to the breadth of international scholarship through a bi-annual publication written and edited by Boston University's undergraduate students. Founded with the intention of promoting dialogue between students, scholars, and policy-makers in an increasingly globalized world, the platform that the IRR creates for emerging scholars is needed now more than ever. The traditional lenses of understanding international relations have shifted in the decade that separates this issue from the first. From anti- government demonstrations and far-right nationalism to the implications of climate change and the global pandemic, the past twelve years have illuminated the extent to which technology and social mobilization have redefined resistance for the generations to come. Despite the unique hardships posed by the global pandemic, the 25th edition preserves the IRR's commitment to illuminating key currents in international affairs that are often neglected by global media. This issue seeks to explore the role of resistance in promoting political reform, thwarting suppression, and accelerating solutions to the world's most pressing crises, whether through the coffeehouses of Egypt or the colonial histories of Latin America

Implicit learning and acquisition of music

Implicit learning is a core process for the acquisition of a complex, rule-based environment from mere interaction, such as motor action, skill acquisition, or language. A body of evidence suggests that implicit knowledge governs music acquisition and perception in nonmusicians and musicians, and that both expert and nonexpert participants acquire complex melodic, harmonic, and other features from mere exposure. While current findings and computational modeling largely support the learning of chunks, some results indicate learning of more complex structures. Despite the body of evidence, more research is required to support the cross-cultural validity of implicit learning and to show that core and more complex music theoretical features are acquired implicitly
