Can a Flavour-conserving Treatment Improve Things ?
In this work I would like to present some ideas on how to improve on the gauge sector in our lattice simulations at finite baryon density. The long standing problem, that we obtain an onset in thermodynamic quantities at a much smaller chemical potential than expected, could be related to an unphysical proliferation of flavours due to hard gluons close to the Brillouin edges. These hard gluons ...
متن کاملFlavour-conserving oscillations of Dirac-Majorana neutrinos
We analyze both chirality-changing and chirality-preserving transitions of DiracMajorana neutrinos. In vacuum, the first ones are suppressed with respect to the others due to helicity conservation and the interactions with a (“normal”) medium practically does not affect the expressions of the probabilities for these transitions, even if the amplitudes of oscillations slightly change. For usual ...
متن کاملConstraints on Phases of Supersymmetric Flavour Conserving Couplings
In the unconstrained MSSM, we reanalyze the constraints on the phases of supersymmetric flavour conserving couplings that follow from the electron and neutron electric dipole moments (EDM). We find that the constraints become weak if at least one exchanged superpartner mass is > O(1 TeV) or if we accept large cancellations among different contributions. However, such cancellations have no evide...
متن کاملO5: Technical Accident Reconstruction-What Can be Learned to Improve Medical Treatment in Trauma Patients
Annually, more than 1 million people were killed in road traffic accidents worldwide every year and an uncounted number were severe injured. In 2012 fatal injuries caused by road traffic accidents are under the top ten lists of causes of death in the world. It´s expected that in the near future road traffic accidents become one of the main causes of death in the world. Most of these fatal injur...
متن کاملCan Neuroscience Improve Addiction Treatment and Policies?
The main target of alcohol and other drug self-administration is the brain. For this reason understanding of brain mechanisms (i.e., neuroscience research) may offer important insights for creating effective prevention and treatment interventions, as well as fair and appropriate drug policies. Fair and appropriate drug policies (public laws and regulations) are expected to reduce the harms of d...
