- On integrating out short-distance physics
-
I submitted an article with simple calculations where the "short-distance physics" is integrated out automatically rather than "manually". http://arxiv.org/abs/1409.8326 Happy reading! Abstract: ...

- Help Me Choose New Physics Benchmarks With Cluster Analysis
-
Yesterday I worked from scratch at a problem which certainly others have already solved in the past. I have mixed feelings with such situations: on one side I hate to reinvent the wheel, especially if there is an easy way to access a good solution; on the ...

- 11. Hide It In The Bulk
-
I remember a funny shirt I once saw at a physics conference- it gave 10 tips on what to do when "everything else fails". Here is the list: 10. Subtract Infinity 9. Add heavy fermions 8. Set all fermion masses to zero 7. Invent another symmetry 6. ...

- Run, Alpha Strong, Run
-
One of the funniest misnomers in particle physics is the naming of coupling strength parameters of the fundamental interactions as "constants". We speak of a fine structure constant (alpha) to address one of the most important parameters of elect ...

- Black Holes May Be Cooler Than We Thought.
-
Stephen Hawking and Jacob Bekenstein made black holes hot, my latest work shows just how cool they really are. I have derived a formula for the temperature of a black hole which has the same basic shape as that derived by Bekenstein and Hawking, but whic ...

- The Plot Of The Week: Higgs Decays To WW In ATLAS
-
The latest paper by the ATLAS Collaboration is a very detailed report of the search for Higgs boson decays to W boson pairs in Run 1 data. The H->WW* process contributes significantly to the total bounty of Higgs boson candidates that the two CERN exper ...

- New Limits On VY Production From CDF: Good, But Also Disappointing
-
Alas, for once I must say I am not completely happy of one new result by the CDF collaboration- the experiment to which I devoted 18 years of my research time, and where I learned almost everything I know about experimental particle physics. ...

- Wave-Particle Duality And Quantum Uncertainty- Two Sides Of The Same Mystery?
-
If you think of quantum physics in terms of information about a system, it is a lot less complicated, according to a new paper. In that context, features of the quantum world previously considered distinct - wave-particle duality and the quantum uncerta ...

- Guest Post: Ben Allanach, On Open Access
-
Ben Allanach, guest blogger, is a Professor of Theoretical Physics at the University of Cambridge. He is grumpy about the way that public funds are being unnecessarily directed to scientific publishing houses. So I am offering this space to him to hear wh ...

- Falsifiability And The Integrity Of Physics
-
Science is what scientist do. And the scientific method is the method scientists follow. A tautology you say? Not according to George Ellis and Joe Silk. In an opinion paper in Nature under the title ' Scientific method: Defend the integrity of physic ...
