Softened Gravity and the Extension of the Standard Model up to Infinite Energy
Attempts to solve naturalness by having the weak scale as the only breaking of classical scale invariance have to deal with two severe difficulties: gravity and the absence of Landau poles. We show that solutions to the first problem require premature modifications of gravity at scales no larger than 10 GeV, while the second problem calls for many new particles at the weak scale. To build model...
متن کاملPRACTICAL PROBLEMS AND THE EFFICACY OF INTRAOSSEOUS INFUSION: SOLVING THE PROBLEMS BY EMPLOYING AN ANIMAL MODEL
In critically ill infants and children, intravascular (IV) access is sometimes very difficult. In such cases intraosseous (IO) infusion should be used as the method of choice. However, in practice, different problems are experienced with this procedure. To overcome the practical problems and to confirm the efficacy of IO infusion in reversing hypovolemic shock, an animal model was used by ...
متن کاملQuantum Gravity with the Standard Model
A unfied theory of four-dimensional gravity together with the standard model is presented, with supersymmetry breaking of M-theory at a TeV. Masses of the known particles are derived. The cosmological constant is quantum generated to the observed value. Quantum corrections to the classical compactification are analyzed, and the scenario is stable.
متن کاملQuantum Gravity and Maximum Attainable Velocities in the Standard Model
A main difficulty in the quantization of the gravitational field is the lack of experiments that discriminate among the theories proposed to quantize gravity. Recently we showed that the Standard Model(SM) itself contains tiny Lorentz invariance violation(LIV) terms coming from QG. All terms depend on one arbitrary parameter α that set the scale of QG effects. In this talk we review the LIV for...
متن کاملQuantum gravity and Lorentz invariance violation in the standard model.
The most important problem of fundamental physics is the quantization of the gravitational field. A main difficulty is the lack of available experimental tests that discriminate among the theories proposed to quantize gravity. Recently, Lorentz invariance violation by quantum gravity (QG) has been the source of growing interest. However, the predictions depend on an ad hoc hypothesis and too ma...
