  • Author(s): Valentin V. Khoze, Daniel L. Milne, and Michael Spannowsky QCD instantons are non-perturbative phenomena predicted to arise from the strong force, but which have not been directly observed. However, they may appear as a large number of soft jets in LHC collisions. In this paper the authors provide a state-of-the-art calculation of the event rate for these signals by making use of the optical theorem and higher-order contributions. Despite...
  • Author(s): Shirley Weishi Li, Luke F. Roberts, and John F. Beacom In this theoretical study of successful core-collapse supernovae, the authors provide a detailed model of neutrino emission from the different phases of the transition - explosion to proto-neutron star cooling to late-time formation of either neutron star or black hole. They show that for a supernova in the Milky Way, these copiously produced neutrinos can be detected by current...
  • Author(s): Tie-Jiun Hou, Jun Gao, T. J. Hobbs, Keping Xie, Sayipjamal Dulat, Marco Guzzi, Joey Huston, Pavel Nadolsky, Jon Pumplin, Carl Schmidt, Ibrahim Sitiwaldi, Daniel Stump, and C.-P. Yuan This work details the release of the CTEQ-TEA collaboration’s updated set of parton distribution functions, CT18. These PDFs are a crucial input to almost all theory and experimental calculations carried out at the LHC and potentially other hadron colliders...
  • Author(s): Theodore Steele and Tobias Baldauf The large-scale structure (LSS) provides a three-dimensional cosmological probe containing significantly more information than the CMB, but its small-scale non-linearities render standard perturbation theory unreliable beyond tree-level. The authors study the bispectrum of the LSS, an important cosmological observable for non-Gaussianity, in the effective field theory approach up to 1-loop order, while...
  • Author(s): Antón Baleato Lizancos, Anthony Challinor, and Julien Carron Measurements of the primordial B modes of the CMB are crucial for testing cosmic inflation. However, gravitational lensing of the CMB photons contaminates these measurements. Here, the authors show, through analytic and numerical work, that the simplest method of removing this contamination, using a template at the gradient level based on lensed E modes, is perhaps unexpectedly...
  • Author(s): Marius Millea, Ethan Anderes, and Benjamin D. Wandelt In this manuscript, the authors propose, test and validate a new inference method that overcomes the limitations of existing algorithms used to deal with the contamination of the B-mode polarization by gravitational lensing. This new algorithm can perform joint inferences of the different cosmological parameters controlling primordial CMB and lensing. It leads to a rigorous check...
  • Author(s): Giorgio Gratta, David E. Kaplan, and Surjeet Rajendran Interactions predicted by beyond-standard-model theories could be detected using a variation on Mössbauer spectroscopy, according to a new proposal. [Phys. Rev. D 102, 115031] Published Thu Dec 24, 2020
