    Electroweak phase transition with a double well done doubly well

    We revisit the electroweak phase transition in the scalar singlet extension of the standard model with a 2 symmetry. In significant parts of the parameter space the phase transition occurs in two steps — includi...

    Top-philic ALP phenomenology at the LHC: the elusive mass-window

    We study the LHC phenomenology of an Axion Like Particle (ALP) that couples only derivatively with the top quark at tree level. We inspect the radiatively induced couplings with the SM fermions and (gauge) bos...

    Axionic domain walls at Pulsar Timing Arrays: QCD bias and particle friction

    The recent results from the Pulsar Timing Array (PTA) collaborations show the first evidence for the detection of a stochastic background of gravitational waves at the nHz frequencies. This discovery has profo...

    Holographic composite Higgs model building: soft breaking, maximal symmetry, and the Higgs mass

    We study the emergence and phenomenological consequences of recently proposed new structures, namely soft breaking of the Higgs shift symmetry and ‘maximal symmetry’ of the composite sector, in holographic rea...

    Bubble-resummation and critical-point methods for \(\beta \) -functions at large N

    We investigate the connection between the bubble-resummation and critical-point methods for computing the \(\beta \) ...

    Extracting the mass scale of a second Higgs boson from a deviation in h(125) couplings

    We investigate the correlation between a possible deviation in the discovered Higgs boson h(125) couplings from the Standard Model prediction and the mass scale (M 2nd) of the next...
