We analyse the constraints of the general two Higgs doublet models by evolving the Yukawa coupling constants to high energy under renormalization group. We consider the appearance of a Landau pole or large off-diagonal Yukawa couplings which cause tree level flavour changing neutral currents. Our study shows the latter condition can be used to answer how much Z 2 symmetry breaking can be allowed

We present the results of a search for relations between observables that are independent of the Chiral Perturbation Theory (ChPT) Next-to-Next-to-Leading Order (NNLO) Low-Energy Constants (LECs). We have found some relations between observables in ππ, πK scattering and Kl4 decay which have been evaluated numerically using fit 10 in [1] for the NLO LECs. We also show some preliminary results for a

With the recent project and publication ‘Fluid Sounds’ (2015-2016) the authors suggested a new format of academic publication named ‘Audio Papers’. The present article wish to develop the audio paper format as a reflective movement in which philosophical, aesthetic and practical attributes are considered.As suggested in Groth & Samson, 2016, the audio paper is an aesthetic academic practice wo

An overview is given of Chiral Perturbation Theory and various applications to eta decays. In particular, the main decay η → 3π is discussed at the one-loop level, and estimates of the higher order corrections are given. The importance of p6 and higher order effects in double Dalitz and η → π0γγ decays is pointed out. In all these cases the need for new experimental results is stressed.

Objective: To investigate if muscle strength and muscle activation patterns are associated with increased knee abduction during two functional tasks, commonly used in rehabilitation for individuals with anterior cruciate ligament reconstruction (ACLR). Design: Cross-sectional study. Setting: Laboratory. Participants: 24 women and 29 men approximately 7 months after ACLR. Main outcome measures: Iso

We report on a calculation of ε′K/εK at next-to-leading in the 1/Nc expansion and to lowest order in Chiral Perturbation Theory. We discuss the short-distance matching, the scale and scheme dependence as well as the long-distance short-distance matching. We include the two known chiral corrections to our result and discuss further order p4 corrections to it.

Exact analytical expressions for the ∆S = 1 coupling Im GE in terms of observable spectral functions are given. This coupling determines the size of the ∆I = 3/2 contribution to ε′ . We show analytically how the scheme-dependence and scale dependences vanish to all orders in 1/Nc and NLO in αS explicitly both for Q7 and Q8 . Numerical results are derived for both Q7 and Q8 from the τ-data and know

Background: Persistent organic pollutants (POPs) have been associated with type 2 diabetes (T2D), but causality is uncertain. Objective: Within longitudinal population-based data from northern Sweden, we assessed how POPs associated with T2D prospectively and cross-sectionally, and further investigated factors related to individual changes in POP concentrations. Methods: For 129 case-controls pair
