Quark mass effects in perturbative thermodynamics
Abstract: Results for several thermodynamic quantities within the next-to-leading order calculation of the thermodynamic potential in perturbative QCD at finite temperature and chemical potential including non-vanishing quark masses are presented. These results are compared to lattice data and to higher-order optimized perturbative calculations to investigate the trend brought about by mass corrections.

Extended Higgs sectors and the alignment limit
Abstract: After the discovery of the first elementary scalar particle–the Higgs boson–it is natural to wonder if additional elementary scalar particles exist in nature. Indeed, given the multiplicity of fermions and vector bosons that make up the Standard Model of particle physics, it would be somewhat surprising if the Higgs sector was of a minimal form, as posited by the Standard Model (SM). However, the current Higgs data suggest that the properties of the observed Higgs boson are very close to those expected in the Standard Model. In this talk, I discuss the required properties of an extended Higgs sector such that one Higgs scalar is approximately SM-like. This can be achieved if one of the scalar mass-eigenstates is nearly aligned in field space with the scalar vacuum expectation value (the so-called alignment limit). Implications of the alignment limit for a variety of Higgs sectors, including supersymmetric extensions of the Standard Model, are examined, and some of the phenomenological implications are considered.
Helsinki Higgs Forum, 14-16 December 2016, Physicum, Kumpula campus
The aim of the Forum is to bring together Higgs physics experts representing its different facets: phenomenology, cosmology and experiment, and create a productive atmosphere for exchange of ideas across the fields.
The Forum is also expected to engage local students and staff providing them with the state of the art in Higgs physics. The format of the meeting assumes plenary talks only as well as a young scientist forum.
