The end of measurement and the last lab / Carney, Daniel (speaker) (Berkeley National Lab)
Measurements in fundamental physics are becoming increasingly difficult. In particular, many high-precision measurements are now dealing with the intrinsic quantum mechanical noise of the detectors themselves. [...]

The Present and Future of Flavor / Bordone, Marzia (speaker) (University of Zürich and CERN)
Flavour physics provides some of the most stringent tests of the Standard Model and a powerful indirect probe of new physics. Precision studies of quark transitions have revealed a striking pattern of masses, mixings, and CP violation that remains unexplained by current theory, while persistent tensions in key observables continue to attract attention [...]

Gravitational waves from first order phase transitions: progress and problems / Hindmarsh, Mark (speaker) (University of Helsinki, University of Sussex)
I review calculations of gravitational waves from the fluid flows generated by first order phase transition in the early universe, summarise the current status in simulations and modelling, and suggest areas where further progress can be made in preparation for the LISA mission..

GW fingerprints of inverse FOPTs / Barni, Giulio (speaker)
Building upon the recently proposed concept of inverse FOPT, we investigate their GW signatures. We outline how these transitions differ thermodynamically and hydrodynamically from standard ones and analyse the resulting GW emission from the plasma. [...]

Cosmological first-order phase transitions with large bubbles: beyond conformal fluid and flat spacetime / Giombi, Lorenzo (speaker) (University of Helsinki)
Using semi-analytical models, we investigate the power spectrum of gravitational waves generated by sound waves in the plasma during a first-order phase transition in new unexplored scenarios. (i) The phase transition is accompanied by a change of the equation of state from that of pure radiation. [...]

From equations of state to gravitational wave spectra / Mäki, Mika (speaker)
The Sound Shell Model provides a computationally efficient way of calculating the gravitational wave spectra of cosmological first-order phase transitions. Based on the Sound Shell Model, we have created the simulation framework PTtools and integrated it with our web-based plotting utility PTPlot. In this talk I will show how to use PTtools and PTPlot to easily compute Sound Shell Model power spectra for arbitrary equations of state. [...]

Gravitational wave production: the interplay between vortical and compressional motions / Salome, Madeline Clara (speaker) (Universite de Geneve (CH))
In the early Universe, during a phase transition, the surrounding plasma is subjected to a fluid motion sourcing gravitational waves. This fluid motion can be composed of compressional and vortical motions. [...]
