Now that the first of the Moriond conferences is over, and just as the second one starts, it is time to have a detached view at the Higgs boson results presented there this far by the CMS and ATLAS collaborations, to summarize where we stand and what new information we have gained since last fall, when some new results appeared for the HCP conference.
Understanding and explaining how the Universe works has always been a ultimate goal for mankind. It is impossible to live our conscious existence without asking ourselves whether there is a meaning, a design, or if our existence is just the result of chance; and to avoid asking ourselves what happens after we die, if we will live again, and similar questions. Accepting our mortality is really hard without embracing a potential explanation, a hope, or some kind of faith.
Last week a new important paper appeared in the Arxiv: "
MSSM Higgs Boson Searches at the LHC:Benchmark Scenarios after the Discovery of a Higgs-like Particle", by M.Carena, S.Heinemeyer, O. Stal, C.Wagner, and G.Weiglein. The paper fills a void that was created after the discovery of the Higgs particle last July by the ATLAS and CMS experiments: a thorough assessment of what constraints on the allowed chunks of SUSY parameter space in the light of the existence of a neutral scalar at 125 GeV.
My physics department in Padova is not a huge place, and yet I usually fail to be aware of what goes on around, since I spend all of my time buried inside my office. This morning, though, I had to pass by a meeting room on my way in, and I thus learned of a workshop about to start. Given my interest for the topic, I decided to attend to at least part of it.
"To date, there is no evidence for SUSY particles and lower limits on the masses are more than 4 GeV for gluinos and more than 20 GeV for squarks and sleptons."
