Neutrinos put cosmic ray theory on ice

The IceCube telescope buried beneath the South Pole has failed to detect any high energy neutrinos accompanying exploding fireballs in space, undermining a leading theory of how cosmic rays are born (Nature 484:351,2012).

Application submitted for Athena Swan Silver Award

Physics has long been a male-dominated subject. To fulfil the department's scientific mission, it is vital that we use the full potential of the population and redress that imbalance. Since 2010, the department has been developing a portfolio of new and existing actions to improve the employment conditions and practice for all staff and students. Good practice benefits everyone, but disproportionately benefits women. These actions, and the critical assessment that led to them, are described in our application for an Athena Swan Silver Award.

New paths to particle dark matter

Date: 
29 Mar 2012 - 2:00pm to 30 Mar 2012 - 4:00pm
Venue: 
dwb
Room: 
Dennis Sciama Lecture Theatre
Audience: 
Specialised / research interest

The aim of this meeting is to discuss recent developments concerning searches for dark matter, as well as relevant astrophysical issues and particle phenomenology. On Thursday 29th March there will be a Half-day Meeting (2-6 pm) to take stock of the field, while Friday 30th March will be devoted to a Workshop (9 am-4 pm) concerning both theory and experiment.

UK Cherenkov Telescope Array Collaboration Meeting March 19-20

Date: 
19 Mar 2012 - 11:00am to 20 Mar 2012 - 3:30pm
Venue: 
dwb
Room: 
Fisher Room
Audience: 
Specialised / research interest

The next bi-annual meeting of UK participants in the Cherenkov Telescope Array project will take place in the Denys Wilkinson Building, Department of Physics, University of Oxford, on 19th and 20th March 2012. We will have one day of science-themed talks and one day of technical-themed talks with plenty of time for interactive discussions.

Younger members of the collaboration, and Oxford physics department members with interests in high-energy astrophysics, astroparticle physics, electronics, and telescope design and construction, are particularly encouraged to attend.

ATLAS Higgs Update

The ATLAS(*) and the CMS experiments today presented updates on their searches for Standard Model Higgs bosons. The results, though impressive, do not yet contain enough data to make any definitive statement about the existence or otherwise of the elusive Higgs.

Both experiments have managed to constrain the possible masses of the Higgs down to a narrow range. For ATLAS that range is 116-130 GeV and for CMS it is 115-127 GeV (where a GeV is approximately the mass energy of a proton).

LHCb reveals exciting hints of New Physics

The LHCb experiment this week announced at the HCP Symposium in Paris a result which, if confirmed, would most likely be the first measurement performed at the LHC at CERN that cannot be understood within the long-established Standard Model of particle physics. This will require a deeper theory of 'new physics' to explain. Oxford is a founding member of the LHCb collaboration and Oxford physicists Mat Charles and Guy Wilkinson were lead analysts in the study presented in Paris.
