Washington: A new branch of research field called new physics could turn our understanding of the universe upside down.

PhD student Matin Mojaza from CP3-Origins, said that new physics is about searching for unknown physical phenomena not known from the current perception of the universe and that such phenomena are inherently very difficult to detect.

Together with colleagues Stanley J. Brodsky from Stanford University in the U.S. and Xing-Gang Wu from Chongqing University in China, Mojaza has now succeeding in creating a new method that can make it easier to search for new physics in the universe.

The method is a so called scale-setting procedure, and it fills out some empty, but very important, holes in the theories, models and simulations, which form the basis for all particle physics today.

Many theories and models in particle physics today has the problem that they, together with their predictions, provide some parameters that scientists do not know how to set.

With the new approach researchers can now completely clean their models for the unknown parameters and thus become better at assessing whether a theory or a model holds water.

The standard model has for the last app. 50 years been the prevailing theory of how the universe is constructed.

One of the Standard Model's major problems is that it cannot explain gravity, and another is that it cannot explain the existence of dark matter, believed to make up app. 25 percent of all matter in the universe. In addition, the properties of the newly discovered Higgs particle, as described in the standard model, is incompatible with a stable universe.

Matin and his Chinese and American colleagues now estimate that there may be a basis for reviewing many scientific calculations to clean the results from uncertainties and thus obtain a more reliable picture of whether the results support or contradict current models and theories.
