Finetuned Cancellations and Improbable Theories
James D. Wells
It is argued that the cancellation model (XYCM) is a good proxy for discussions of finetuned cancellations in physical theories. XYCM is then analyzed from a statistical pers…
Probing the pre-BBN universe with gravitational waves from cosmic strings
Yanou Cui, Marek Lewicki, David E. Morrissey +1
Many motivated extensions of the Standard Model predict the existence of cosmic strings. Gravitational waves originating from the dynamics of the resulting cosmic string network ha…
Implications of an Improved Neutron-Antineutron Oscillation Search for Baryogenesis: A Minimal Effective Theory Analysis
Christophe Grojean, Bibhushan Shakya, James D. Wells +1
Future neutron-antineutron (-) oscillation experiments, such as at the European Spallation Source and the Deep Underground Neutrino Experiment, aim to find first evidenc…
Naturalness, Extra-Empirical Theory Assessments, and the Implications of Skepticism
James D. Wells
Naturalness is an extra-empirical quality that aims to assess plausibility of a theory. Finetuning measures are often deputized to quantify the task. However, knowing statistical d…
The role of positron polarization for the inital GeV stage of the International Linear Collider
Keisuke Fujii, Christophe Grojean, Michael E. Peskin +22
The International Linear Collider is now proposed with a staged machine design, with the first stage at ~250 GeV and an integrated luminosity goal of 2~ab. One of…
Exotic Sterile Neutrinos and Pseudo-Goldstone Phenomenology
Bibhushan Shakya, James D. Wells
We study the phenomenology of a light (GeV scale) sterile neutrino sector and the pseudo-Goldstone boson (not the majoron) associated with a global symmetry in this sector that is…
