I found the Higgs!by Rika Takahashi Two little visitors at show off the souvenirs they received at KEK's open house, held on Sunday, 2 September. The girl on the right was very happy to find a "Higgs" in her toy capsule given away at the ILC exhibit. Visitor numbers have increased dramatically from last year's open house, probably due to a special kind of Higgs mechanism that attracts the general public to particle physics.

LCpediaBeam bunchby Daisy Yuhas Particles in a collider aren’t necessarily evenly dispersed along the beam path. Instead they’re often clumped together in bunches with space in between. The series of bunches are sometimes called a bunch train, a pulse, or simply ‘the beam’.

Director's CornerUpdating the European Strategy for Particle Physicsby Barry Barish The particle physics communities worldwide are undertaking strategic planning processes that will set out the course of the field for the coming years. Recent science results, such as the discovery of the Higgs-like particle and the measurement of a relatively large value of theta13, open up exciting future possibilities. In Europe, the process of developing an update to the European Strategy for Particle Physics is under way. The next major step will be an open symposium in Krakow, Poland, from 10 to 12 September, for which a set of linear-collider input documents has been submitted.

from Physics World3 September 2012Special Report: Japan
The 19-member committee not only recommended that Japan should take a lead in the design for a collider to study the Higgs boson, such as the International Linear Collider, but also that it should lead on plans to build a large-scale neutrino facility to study charge-parity violations in neutrino oscillations.
