The original ideas The original ideas for introducing supersymmetry dates back in the 1960s when, in the context of hadron physics that was found to be approximately spin-flavour independent, a symmetry between mesons and baryons was proposed. These…

Read moreThe LHC has started its Run2, exploring for the first time the high-energy frontier at 13 TeV. Collected data will give decisive information on the dynamics behind electroweak symmetry breaking and allow testing the weak-scale naturalness. A TH…
Read moreA half-day workshop took place last week at CERN on Hagedorn’s Legacy. It provided the forum for discussing the past, present and future of Hagedorn’s contributions to physics, 50 year’s after the publication of his seminal Nuovo Cimento paper on…
Read moreGuido Altarelli passed away on September 30th, the TH group bid farewell him: "Many memories rush to mind, as tears to our eyes. His ironic humour, his warmth, his kindness, his integrity, his magnificent smile. A pillar of our group is gone. His…
Read moreApril 28th would have marked the 92nd birthday of Bruno Zumino, who died last year. The Theory Group organized a meeting around this date to honour his memory and to discuss his legacy. The presentations with slides and videos can be found here. …
Read moreThe TH Institute on "Neutral Naturalness", focussing on theories which aim to address the hierarchy problem and feature color-neutral top partner fields was held at CERN/TH from 23 to 26 April 2015. The systematic study of "neutral naturalness":…
Read moreThe 2015 CERN Winter School on Supergravity, Strings, and Gauge Theory took place, from Monday, February 2 to Friday, February 6, at CERN. It was organized by J. Drummond, K. Papadodimas, B. Pioline of the CERN Theory Division and sponsored by the…
Read moreIn 2014, the CERN Theory Unit has continued to play a leading role as a reference center in all areas of theoretical particle physics. Its research covers a wide spectrum ranging from Standard Model physics directly related to the LHC, to formal…
Read moreOur understanding of the early Universe has greatly increased in the past few years due to the high-quality observational data on the cosmic microwave background and large scale structure. The unprecedented precision of the Planck results enabled…
