ILC starts at 500 GeV and goes down in energy

| 25 June 2015 The default collision of the energy of the ILC has always been 500 GeV with promises of an upgrade to 1000 GeV. A while ago, alternative scenarios of a staged ILC that would start at 250 GeV and ramp to 500 GeV later were discussed. All scenarios were evaluated in the community and Hitoshi Murayama reports on the result: the ILC would start at 500 GeV, then go down to lower energies before possibly receiving an upgrade to even higher ones.

LHC is back in business

11 June 2015 On 3 June, the Large Hadron Collider (LHC) at CERN started delivering physics data for the first time in 27 months at the record energy of 13 TeV. This marks the start of season 2 at the LHC, opening the way to new discoveries. The LHC will now run round the clock for the next three years."Run 2 of the LHC can well decide the future of the field. I’m super excited!" said LCC deputy director and theorist Hitoshi Murayama on the day. Category: Image of the week | Tagged: , , , ,

Ready for the jump

| 19 March 2015 The Large Hadron Collider is about to start up again as an almost new machine and almost twice the previous collision energy. With first beams possibly circulating by the end of the month and first collisions expected for the beginning of summer, physicists around the world cannot wait to see what the collisions of Run 2 will reveal. Will there be first signs of supersymmetry, a possible key to the as yet locked dark universe? What will the properties of the Higgs boson reveal? Will there be unexpected peaks in the data? And how do these results translate to the ILC? LC NewsLine speaks to two theoretical physicists. Category: Feature | Tagged: , , , , , , , , ,

The Higgs is Different

| 5 July 2012 The Higgs is Different, says Jonathan Bagger, a theoretical physicist and chair of the International Linear Collider Steering Committee ILCSC. It has no spin, it fills the vacuum, but most importantly, it opens the door to a new range of questions. Questions which a linear collider with its clean and controlled collisions could help answer.

From CERN Bulletin: Much ado about Nothing – exploring the vacuum with the LHC

3 May 2012 Empty space is anything but. Remove everything you can from an area of space and it will still bustle with activity. A veritable abundance of particles and all-pervasive fields fill space with energy. Empty space even weighs something. Indeed, studying ‘nothing’ can tell us almost everything about the universe we live in.

Celebrating first 7-TeV collisions at the LHC

| 8 April 2010 This past week marked the beginning of a new era for particle physics with the much publicised achievement of establishing the first 7-TeV collisions at the CERN Large Hadron Collider (LHC). [...] We should soon begin to have a glimpse of Terascale physics from searches for the origin of mass to looking for evidence of a new symmetry in nature that could even explain the dark matter. Even more intriguing is the real possibility for totally unexpected surprises that are awaiting us. We are looking to LHC science to establish what kind of lepton collider will be needed to best exploit the energy frontier in the longer term. Category: Director's Corner | Tagged: , , , , , ,

Cosmic Dark Matter and the ILC

| 8 November 2007 A couple of weeks ago, Michael Peskin (SLAC) opened the ALCPG07 meeting at Fermilab with a visionary talk titled, "The Physics Landscape: Now and Tomorrow." Category: Director's Corner | Tagged: , ,
