EPJ Web of Conferences, 2014 Searches for the Higgs boson at CMS, based on the data collected in 2011 and 2012 at 7 and 8 TeV centre-of-mass energy, corresponding to integrated luminosities of 5 and 20 fb−1, are presented. The observed new boson is found to be consistent with the Standard Model Higgs boson in all investigated properties such as the spin and couplings to bosons and

How opposing ideological groups use online interactions to justify and mobilise collective action
European Journal of Social Psychology, Volume 52, Issue 7, Page 1082-1110, December 2022., 2022 Abstract The purpose of this pre‐registered study was to investigate how different ideological groups justified and mobilised collective action online. We collected 6878 posts from the social media accounts of pro‐Black Lives Matter (n = 13) and anti‐Black Lives Matter (n = 9) groups who promoted collective action in the month after George Floyd's ...

Biogeomorphic recovery of a river reach affected by mining
Earth Surface Processes and Landforms, Volume 47, Issue 15, Page 3497-3514, December 2022., 2022 The Grogwynion reach of the River Ystwyth,Wales, affected by mining in the 19th and 20th centuries, has shown a progressive reversion to a sinuous single‐channel planform since 2001 from an active braided pattern. A critical factor has been a change in the extent and type of riparian vegetation occurring within the active zone of the river due to the ...

The scale of new physics from the Higgs couplings to γγ and γZ
Journal of High Energy Physics, 2022 Measuring the Higgs couplings accurately at colliders is one of the best routes for finding physics Beyond the Standard Model (BSM). If the measured couplings deviate from the SM predictions, then this would give rise to energy-growing processes that ...

Boomerang webs up to three-loop order
Journal of High Energy Physics, 2021 Webs are sets of Feynman diagrams which manifest soft gluon exponentiation in gauge theory scattering amplitudes: individual webs contribute to the logarithm of the amplitude and their ultraviolet renormalization encodes its infrared structure.

The role of sense of community in improving the health‐related quality of life among Black Americans
Journal of Community Psychology, Volume 51, Issue 1, Page 251-269, January 2023., 2023 Abstract Black Americans have the lowest life expectancy and health‐related quality of life (HRQoL; a strong predictor of premature mortality) of any racial/ethnic group in the United States. Low rates of physical activity and engagement in healthy eating are two known contributors to low HRQoL.

What can we learn from the total width of the Higgs boson? [PDF]
, 2021 As one of the key properties of the Higgs boson, the Higgs total width is sensitive to global profile of the Higgs boson couplings, and thus new physics would modify the Higgs width. We investigate the total width in various new physics models, including various scalar extension, composite Higgs models, and fraternal twin Higgs model.

Classical Yang-Mills observables from amplitudes
Journal of High Energy Physics, 2020 The double copy suggests that the basis of the dynamics of general relativity is Yang-Mills theory. Motivated by the importance of the relativistic two-body problem, we study the classical dynamics of colour-charged particle scattering from the ...

Correlation of theoretical uncertainties in PDF fits and theoretical uncertainties in predictions
European Physical Journal C: Particles and Fields, 2021 We show how to account for correlations between theoretical uncertainties incorporated in parton distribution function (PDF) fits, and the theoretical uncertainties in the predictions made using these PDFs.
