A model solving the PVLAS-CAST puzzle
Axion physics has received a boost with the recent claim of the PVLAS collaboration. Their results can be interpreted as due to a new axionlike particle but the CAST collaboration has not found trace of it. While the axionlike particle interpretation of the PVLAS signal is going to be probed by dedicated laboratory experiments, it is mandatory to find either alternatives to it or models in whic...
متن کاملReconciling the CAST and PVLAS results.
The PVLAS experiment has recently claimed evidence for an axionlike particle in the milli-electron-volt mass range with a coupling to two photons that appears to be in contradiction with the negative results of the CAST experiment searching for solar axions. The simple axion interpretation of these two experimental results is therefore untenable and it has posed a challenge for theory. We propo...
متن کاملCompatibility of cast search with axionlike interpretation of PVLAS results.
The PVLAS Collaboration has results that may be interpreted in terms of a light axionlike particle, while the CAST Collaboration has not found any signal of such particles. We propose a particle physics model with paraphotons and with a low energy scale in which this apparent inconsistency is circumvented.
متن کاملSolving a Binary Puzzle
A Binary puzzle is a Sudoku-like puzzle with values in each cell taken from the set {0, 1}. Let n ≥ 4 be an even integer, a solved binary puzzle is an n × n binary array that satisfies the following conditions: (1) no three consecutive ones and no three consecutive zeros in each row and each column; (2) the number of ones and zeros must be equal in each row and in each column; (3) there can be ...
متن کاملIntroducing an Invention: Puzzle Shaped Cast for Upper Limb Fractures
Upper limb fractures are prevalent injuries. An essential element of fracture healing is to maintain the bones alignment. However there are lots of complications associated with traditional ways of treatment, such as compartment syndrome and stiffness due to immobility for long time. Also evaluation and observation of the limb under the casts for potential infections and skin issues are n...
