Divergences in anomalous dimension matrices of quarks at three loops: Explanation and simple solution
Adrian Lewandowski
Three-loop counterterms for the Standard Model (SM) revealed that the matrix of anomalous dimensions () of quarks is divergent in the limit unless a carefully chosen n…
Vector-scalar mixing to all orders, for an arbitrary gauge model in the generic linear gauge
Adrian Lewandowski
I give explicit fromulae for full propagators of vector and scalar fields in a generic spin-1 gauge model quantized in an arbitrary linear covariant gauge. The propagators, express…
LSZ-reduction, resonances and non-diagonal propagators: gauge fields
Adrian Lewandowski
We analyze in the Landau gauge mixing of bosonic fields in gauge theories with exact and spontaneously broken symmetries, extending to this case the Lehmann-Symanzik-Zimmermann (LS…
LSZ-reduction, resonances and non-diagonal propagators: fermions and scalars
Adrian Lewandowski
We analyze in details the effects associated with mixing of fermionic fields. In a system with an arbitrary number of Majorana or Dirac particles, a simple proof of factorizability…
Conformal Standard Model, Leptogenesis and Dark Matter
Adrian Lewandowski, Krzysztof A. Meissner, Hermann Nicolai
The Conformal Standard Model (CSM) is a minimal extension of the Standard Model of Particle Physics based on the assumed absence of large intermediate scales between the TeV scale…
Ultraviolet cutoffs and the photon mass
Piotr H. Chankowski, Adrian Lewandowski, Krzysztof A. Meissner
The momentum UV cutoff in Quantum Field Theory is usually treated as an auxiliary device allowing to obtain finite amplitudes satisfying all physical requirements. It is even absen…
Two-loop RGE of a general renormalizable Yang-Mills theory in a renormalization scheme with an explicit UV cutoff
Piotr H. Chankowski, Adrian Lewandowski, Krzysztof A. Meissner
We perform a systematic one-loop renormalization of a general renormalizable Yang-Mills theory coupled to scalars and fermions using a regularization scheme with a smooth momentum…
Conformal Standard Model with an extended scalar sector
Adam Latosinski, Adrian Lewandowski, Krzysztof A. Meissner +1
We present an extended version of the Conformal Standard Model (characterized by the absence of any new intermediate scales between the electroweak scale and the Planck scale) with…
Softly broken conformal symmetry and the stability of the electroweak scale
Piotr H. Chankowski, Adrian Lewandowski, Krzysztof A. Meissner +1
We point out a novel possible mechanism by which the electroweak hierarchy problem can be avoided in the (effective) quantum field theory. Assuming the existence of a UV complete u…
Gauge invariance of the amplitude
Pior H. Chankowski, Adrian Lewandowski
We point out that the one-loop amplitude of the decay is gauge invariant owing to a particular relation between the trilinear couplings and the Higgs boson mass.…
Renormalization of Nielsen Identities
Adrian Lewandowski
We study renormalization of identities governing the dependence of 1PI Green's functions on gauge-fixing parameters. For general dimensionally regularized Yang-Mills theories with…
