A Search for New Physics Processes using Dijet Events
The ATLAS Experiment has extended the energy frontier of searches for new particles and new processes beyond those of the Standard Model by studying collision events with so-called "dijets".

Is Nature Supersymmetric?
String Theory predicts a new symmetry, called "supersymmetry", that could shed light on some of today's mysteries of fundamental particles and interactions. In supersymmetry, every particle-type should have a "shadow" particle called a super-partner that (in general) has a much higher mass. The ATLAS Experiment has analyzed the first year of its LHC data and searched for evidence of these super-partners of ordinary matter.

ATLAS Experiment Reports Its First Physics Results from the LHC
The first physics results from the ATLAS Experiment with proton-proton collisions at an energy of 0.9 TeV in late 2009 have now been accepted for publication in the journal Physics Letters B.

First collisions in ATLAS
A few days ago, loud cheers and happy faces filled the ATLAS Control Room while the whole detector lit up: protons are back at the experiment's door, and everybody forgot in a second the long year of waiting for the Large Hadron Collider (LHC) to resume operation.

LHC beams and events back in ATLAS
Loud cheers and happy faces fill the ATLAS Control Room while the whole detector lights up: protons are back today at the experiment's door, and everybody forgets in a second the long year of waiting for the Large Hadron Collider (LHC) to resume operation.

Higgs finds the Higgs at RAL
On Friday, March 13th, British high school student Jonathan Higgs discovered the elusive Higgs boson among the simulated particle tracks in Minerva – a special form of ATLAS' event display program, Atlantis, designed for students in the International Particle Physics Masterclasses.

A comic takes on CERN
If you want insight into the lives of graduate students, look no further than Jorge Cham’s Piled Higher and Deeper comic series, detailing the trials and tribulations of earning a PhD. He brought his well-honed observational humour to CERN, meeting with a few graduate students and post-docs for a slice of life at the world’s largest physics experiment.

A Wall ATLAS
Twenty-eight-year-old Josef Kristofoletti is a traveling artist. On the site documenting the work of his group, transitantenna.com, he writes: "I am taking a survey of American mural painting in all of its forms, looking for the best pictures across the land, and painting some along the way." One of these paintings is an image of the ATLAS detector, a 13 x 7 metre mural on the side of the Redux Contemporary Art Center in South Carolina, entitled "Angel of the Higgs Boson".

ATLAS preparing for collisions in mid-2009
The full ATLAS Experiment has been operational and taking cosmic ray data since September 2008, and high-energy collisions are scheduled for late summer 2009. Data from cosmic rays that hit the ATLAS detector are valuable to calibrate and synchronize the many detector elements. Even more exciting were the so-called “splash events” that occurred as the LHC was being tuned up starting 10 September 2008.

First beam and first events in ATLAS
ATLAS experimenters celebrated today as the first beams circulated the Large Hadron Collider in both directions. While everyone was cheering in the LHC control room, the cheers were echoed in the ATLAS and other control rooms, and in several auditoriums around CERN.

Football and Modern Art for ATLAS
This time the outside ATLAS overview week was held in a somewhat unusual venue for a physics meeting. All the plenary sessions were organized inside the VIP area of the famous soccer stadium "Stade de Suisse" just outside the city center of Bern. I was one of the few participants of the meetings that had previously been in this stadium and moreover I was honored to be the coach of one of the two ATLAS soccer teams composed specially for the meeting. Thus when I was asked to give my impressions from the meeting, I thought I should mostly share my analysis and personal view of the first ATLAS soccer game and I happily accepted.

Socio-Economic Perspectives on ATLAS
Building the ATLAS detector has been a mammoth and innovative project. Sociologists, economists, and entrepreneurs have studied how such projects benefit society and the economy. The ATLAS collaboration has a number of unique characteristics, because of the size of the project, together with its complex scientific nature. It is the largest collaborative effort ever attempted in the physical sciences with more than 2200 physicists from 38 countries.

From Exotic Particles to Possible Solutions for Blindness
The search for exotic particle has led Alan Litke and his ATLAS colleagues to design a system that has allowed the discovery of a new type of cell in the retina of primates, and this technology is helping to find solutions for certain types of blindness.

German Chancellor Merkel visits ATLAS
German Federal Chancellor Angela Merkel made a historic visit to CERN at the end of last month. During her brief 1.5 hours on site, she was taken on a whistle-stop tour of the ATLAS control room and cavern, and given the chance to look down on the largest particle physics experiment in the world from a dizzying height of 100 metres through the access shaft which links the massive underground cavern to the surface.

Argentina, Chile and Colombia Join ATLAS Experiment
The ATLAS collaboration is continuously expanding, and recently its message has reached new shores – South America. Three new countries, Argentina, Chile and Colombia joined the collaboration at the beginning of the year, when Peter Jenni, ATLAS spokesperson, signed collaboration agreements formalising the presence of the Latin American research teams within the ATLAS experiment.

Great Interest as ATLAS and CERN Open to Public
They say there’s no such thing as bad publicity, but how would recent attempts in a Hawaiian court to stop the opening of the LHC because of safety concerns affect the general public’s perception of CERN? The Open Day on 5-6 April gave the ATLAS Collaboration a chance to find out.

Atlas.ch Website Surpasses 1 Million Hits in 2007
The anticipation on site in Switzerland is tangible as the final steps in the construction of the ATLAS detector get underway, ahead of the LHC switch-on later this year. But whilst all the hard work is going on down in the pit, a small team of people are toiling equally hard to bring that sense of excitement and wonder out into the wider world, and throw open a window onto what will be the biggest experiment in the history of human kind.
