Forskningsöversikt (refereegranskat)abstract
- The goal of this report is to summarize the current situation and discuss possible search strategies for charged scalars, in non-supersymmetric extensions of the Standard Model at the LHC. Such scalars appear in Multi-HiggsDoublet models, in particular in the popular Two-HiggsDoublet model, allowing for charged and additional neutral Higgs bosons. These models have the attractive property that electroweak precision observables are automatically in agreement with the Standard Model at the tree level. For the most popular version of this framework, Model II, a discovery of a charged Higgs boson remains challenging, since the parameter space is becoming very constrained, and the QCD background is very high. We also briefly comment on models with dark matter which constrain the corresponding charged scalars that occur in these models. The stakes of a possible discovery of an extended scalar sector are very high, and these searches should be pursued in all conceivable channels, at the LHC and at future colliders.

- Over the past years there has been increasing interest in physical activity promotion and the development of appropriate policy. So far, there has been no comprehensive overview of the activities taking place in Europe in this area of public health policy.Methods:Using different search methods, 49 national policy documents on physical activity promotion were identified. An analysis grid covering key features was developed for the analysis of the 27 documents published in English.Results:Analysis showed that many general recommendations for policy developments are being followed, for example: general goals were formulated, an implementation plan was included, a timeframe and a responsible body for the implementation was often specified. However, limited evidence for intersectoral collaboration was found. Quantified goals for physical activity were the exception. Population groups most in need such as people with low levels of physical activity were rarely specifically targeted. Most policies emphasized the importance of an evaluation. However, only about half of them indicated a related intention or requirement.Conclusion:In recent years there has been a noticeable development of national policy documents on physical activity promotion. Following principles for policy development more closely could increase the effectiveness of their preparation and implementation further.
