Effective field theory: New physics through precision measurements<\/p>\n
Date: 17 February 2017, 13:45 – 14:45
\nVenue: Physics C36
\nSpeaker: Dr Chris Hays, Oxford<\/p>\n
With the discovery of the Higgs boson, the Standard Model (SM) is complete. Yet the SM is itself an incomplete description of nature. One strategy to go beyond this model is to search for new processes through SM measurements. An effective field theory (EFT) describes the impact of these processes as small deviations from the SM in orders of the inverse scale of new physics. A complete fit of the EFT operator coefficients provides a generalised probe for new physics. I discuss the potential for such a fit, focusing on the contributions from precision Higgs and electroweak measurements.<\/p>\n

(Tech.), is Finland\u2019s first Professor of Solar Economy at Lappeenranta University of Technology (LUT) and his research focus in the area of renewable energy. Professor Breyer came to LUT from Reiner Lemoine Institute in Germany, where he worked as managing director and scientific director. He earned his doctorate from the University of Kassel in Germany in 2012 for his research on the “Economics of Hybrid Photovoltaic Power Plants”. Prior to that he worked several years in the research and development and market development department of Q-Cells, a former world market leader in solar cell manufacturing and solar power plant engineering. www.researchgate.net\/profile\/Christian_Breyer<\/a> http:\/\/www.neocarbonenergy.fi\/<\/a> vision at https:\/\/youtu.be\/Ww76jNrVHhw<\/a><\/p>\n Nuno Bimbo<\/strong><\/p>\n <\/p>\n Derek Ward-Thompson at UCLan has asked me to circulate the invitation to staff here at Lancaster.

Astrophysics Seminar – Soft X-ray sources\/novae – 24th Feb <\/strong><\/h2>\n
\nSuper-Soft X-ray Sources (SSS) are a small class of X-ray sources characterised by a blackbody-like spectrum of effective temperature
\n30-100 eV (several 10^5 K) and luminosities above 10^36 erg\/s. Owing to their softness, galactic SSS are more difficult to observe and interpret because of high galactic extinction and uncertain distances, respectively. While a small number of permanent SSS are known since the 80s, novae have been predicted to pass through a phase of SSS emission that has indeed been observed with, e.g., ROSAT, BeppoSAX, or ASCA.
\nAttempts of spectral modeling of nova SSS spectra ranged from blackbody fits to most refined local thermodynamic equilibrium (LTE) and non-LTE atmosphere modeling, but the low resolution of CCD spectra allows no unique constraint of spectral parameters of complex models. The X-ray grating spectrometers on board XMM-Newton and Chandra allow much more detailed analysis of SSS spectra and, as always in nature, the truth is much more complicated than believed. I will first present historic observations and attempts of interpretation, and then show the grating spectra with the details. A large variety in grating spectra of canonical SSS spectra and those of novae emerged, and I will show approaches how to find trends and to explain some commonalities.
\nSpectral modeling is currently not possible, but I will present and discuss some approaches.<\/p>\nThe Physics of Cartoons <\/strong><\/h2>\n
