Goldstone bosons across thermal phase transitions
Peter Lowdon, Owe Philipsen
Temperature has a significant effect on the properties of quantum field theories (QFTs) with a spontaneously broken symmetry, in particular on the massless Goldstone bosons that ex…
Constraints on Kinetic Mixing of Dark Photons from Dilepton Spectra
A. W. Romero Jorge, E. Bratkovskaya, T. Song +1
Dark photons, the hypothetical gauge bosons associated with an additional symmetry, can couple to Standard Model particles through a small kinetic mixing parameter…
Supercooled Audible Axions
Christopher Gerlach, Daniel Schmitt, Pedro Schwaller
In the audible axion mechanism, axion-like particles source primordial gravitational waves via their coupling to a dark Abelian gauge field. The original setup, however, relies on…
Production of Pairs Through Decay of Meson
Xin-Nan Zhu, Xin-Li Sheng, Defu Hou
We develop a theoretical framework for the production of pairs through the decay of mesons produced from a thermal background, based on the Nambu-Jona-Lasinio (NJL) mo…
The effect of recoils on soft-drop-groomed observables in -tagged jets in a multistage approach
Y. Tachibana, C. Sirimanna, A. Majumder +49
We investigate medium-induced modifications to jet substructure observables that characterize hard components in central Pb-Pb collisions at ~TeV. Using a multi…
Goldstone bosons at non-zero temperature
Peter Lowdon, Owe Philipsen
Spontaneous symmetry breaking in quantum field theories at non-zero temperature still holds fundamental open questions, in particular what happens to vacuum Goldstone bosons when t…
