Abstract 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) bosons and the associated productio

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

Abstract 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 profound implications for the physics

Abstract 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 realizations of composite Higgs

Abstract We investigate the connection between the bubble-resummation and critical-point methods for computing the $$\beta $$ β -functions in the limit of large number of flavours, N, and show that these can provide complementary information. While

Abstract We compute the β-function for a massless Yukawa theory in a closed form at the order O 1 / N f $$ \mathcal{O}\left(1/{N}_f\right) $$ in the spirit of the expansion in a large number of flavours N f . We find an analytic expression with a fi

Abstract 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-to-lightest Higgs boson in models with non-minimal Higgs sec

We present a novel realization of a composite Higgs, which can naturally produce top partners above the current LHC bounds without increasing the tuning above 10%. The essential ingredients are softened breaking of the Higgs shift symmetry as well as

The dynamical generation of right-handed-neutrino (RHN) masses in the early Universe naturally entails the formation of cosmic strings that give rise to an observable signal in gravitational waves (GWs). In this paper, we show that a characteristic b

There was an error in the computation of the n-loop part of the scalar self-energy in our paper [1].
