The virtues of neural networks as unbiased function approximants make them particularly suited for this task. An algorithm that implements this idea is constructed, as a straightforward application of the likelihood-ratio hypothesis test.

I will describe a model where we raise the QCD confinement scale. This can generate a first-order phase transition and triggers electroweak breaking. This provides a baryogenesis scenario with many other cosmological consequences. text/html 2019-10-02T15:26:34+00:00 Anonymous (anonymous@undisclosed.example.com) https://particlevm.physics.ucdavis.edu/seminars/doku.php?id=2018:oct:vainshtein&rev=1570055194&do=diff Arkady Vainshtein On Vacuum Angle (In)dependence in the Higgs Regime Oct. 29, 2018 [pdf file] text/html 2019-07-23T16:43:15+00:00 Anonymous (anonymous@undisclosed.example.com) https://particlevm.physics.ucdavis.edu/seminars/doku.php?id=2018:oct:zan&rev=1563925395&do=diff Bernardo Zan  Walking, weakly first order phase transitions and complex CFT Oct. 23, 2018 [pdf file] text/html 2019-08-13T16:38:49+00:00 Anonymous (anonymous@undisclosed.example.com) https://particlevm.physics.ucdavis.edu/seminars/doku.php?id=2018:oct:zhong&rev=1565739529&do=diff Yiming Zhong Cooling self-interacting dark matter halos Oct. 8, 2018 Room: 432 Abstract: Dark sector models naturally introduce elastic and dissipative self-interactions of dark matter. The heat exchange induced by the elastic scattering permits the gravothermal evolution of the halo. Through the evolution, the inner halo firstly develops a core but ultimately becomes cuspy. Based on a semi-analytic fluid model calibrated with N-body simulations, we find that a mild dissipative scattering c…
