104. The search for sterile neutrinos at the FCC-ee

Oliver Fischer (Unibas)

Physics

Oral

Sterile neutrinos are among the most attractive (but also hardest to test) extensions of the SM to generate the light neutrino masses observed in neutrino oscillation experiments. When the sterile (heavy) neutrinos have masses around the electroweak scale, they can be efficiently searched for at the FCC-ee. In this talk I review the most efficient search channels, present updated estimates...

143. Imprints of compositeness in Higgs and Top sectors at the FCC-ee

Stefania De Curtis (Universita e INFN, Firenze (IT))

Physics

Oral

Future e+e- colliders have a great potential for the Higgs and the Top-quark physics, not only as a test of the SM but also for New Physics (NP) indication. Theoretical arguments supporting the importance of sub-percent Higgs coupling precision measurements continue to grow, especially to find hints for non-SM Higgs: how can we decide if it is the elementary SM Higgs or a composite state...

258. Effective electromagnetic coupling

Graziano Venanzoni (INFN)

12/04/2016, 16:00

Physics

Oral

We propose a measurement of the effective electromagnetic coupling in the space-like region extracted from Bhabha scattering data. We argue that this new method may become feasible at present and future lepton colliders resulting in an alternative determination potentially competitive with the accuracy of the present methods.

132. High Energy Jets at 100 TeV

Dr Jennifer Smillie (Higgs Centre for Theoretical Physics)

Physics

Oral

The production of multiple hard jets in hadronic collisions takes on a different character as the centre-of-mass energy increases. The importance of higher-order terms in the perturbative series (and therefore of higher multiplicity events in inclusive samples) is enhanced both because of the massive increase in phase space and due to the large logarithmic corrections at all orders. The High...

105. Testable SUSY spectrum from GUTs at the FCC-hh

Prof. Stefan Antusch (University of Basel)

12/04/2016, 16:30

Physics

Oral

Grand Unified Theories (GUTs) are attractive candidates for more fundamental elementary particle theories. They can not only unify the Standard Model (SM) interactions but also different types of SM fermions, in particular quarks and leptons, in joint representations of the GUT gauge group. We discuss how comparing predictive supersymmetric GUT models with the experimental results for quark...

96. Characteristic signals of right-handed currents at future colliders

Tomasz Jelinski (University of Silesia)

12/04/2016, 16:45

Physics

Oral

The perspectives on the detection of right-handed currents at future experiments will be discussed. We shall focus on processes with 2 or 4 leptons and jets in the final state. Such processes are expected to give important insight into the structure of couplings of heavy gauge bosons to leptons, including heavy neutrinos, and into the Higgs sector of the BSM model under consideration. We show...
