137. UHE neutrinos and Z'/W'

M. Florian Lyonnet (LPSC)

Theory

YSF (Young Scientists Forum)

A wide range of models beyond the Standard Model predict charged and neutral resonances, generically called W′- and Z′-bosons, respectively. During this talk I will present our study on the impact of such resonances on the deep inelastic scattering of ultra-high energy neutrinos as well as on the resonant charged current ν¯ee− scattering (Glashow resonance). We find that the effects of such...

99. Model-independent analysis of scenarios with heavy vector-like top partners

Theory

YSF (Young Scientists Forum)

While a fourth generation of quarks is now strongly disfavored from the LHC results, many New Physics models predict the existence of new Vector-Like quarks as smoking gun signatures. Searches for new fermionic states heavier than the top quark are being pursued by the CMS & ATLAS collaborations, pushing the mass bounds towards the TeV scale. In this talk, I will review the phenomenology...

123. The New Muon g-2 Experiment at Fermilab

YSF (Young Scientists Forum)

The measurement of the anomalous magnetic moment of the muon provides a test of the standard model and a handle on physics beyond the standard model. There is currently a three sigma discrepancy between theory and experiment. With 20 times the statistics and a factor of four improvement in the systematic errors, a new experiment at Fermilab aims to resolve this difference. I will present the...

110. Gamma lines and cosmic continuum from DM decay

Tiziana Scarna (ULB)

Theory

YSF (Young Scientists Forum)

We show that there exists only a quite limited number of higher dimensional operators which can naturally lead to a slow decay of dark matter particles into monochromatic photons. As each of these operators inevitably induces decays into particles other than photons, we show that the gamma-lines it induces are always accompanied by a continuum flux of cosmic rays. Hence constraints on...
