Pseudo Goldstone Bosons phenomenology in Minimal Walking Technicolor

Abstract

We construct the non-linear realized Lagrangian for the Goldstone Bosons associated to the breaking pattern of SU(4) to SO(4). This pattern is expected to occur in any Technicolor extension of the standard model featuring two Dirac fermions transforming according to real representations of the underlying gauge group. We concentrate on the Minimal Walking Technicolor quantum number assignments with respect to the standard model symmetries. We demonstrate that for, any choice of the quantum numbers, consistent with gauge and Witten anomalies the spectrum of the pseudo Goldstone Bosons contains electrically doubly charged states which can be discovered at the Large Hadron Collider.

Search for technipions in exclusive production of diphotons with large invariant masses at the LHC

“…Such scenarios feature pseudo-scalar technipion states that are remnants of the EWSB in models with more than one weak techniquark doublet. Discovery of such technipions is often considered as one the basic observational signatures of TC [20][21][22]. In extended TC scenarios with colorless (or colored) techniquarks the technipion can be produced via gluon-gluon and quark-antiquark fusion through a strong technipion coupling to heavy t, b quarks (or techniquark-gluon coupling).…”

Anapole dark matter at the LHC

“…One recent study in[24] investigated similar collider signals for a model with a heavy Majorana neutrino being the dark matter.…”

Corrections to (Pseudo)Scalars Decay into a Fermion Pair from Gravitational Torsion

“…As it is expected, for higher gravitational scales the correction decreases due to the quadratic suppression (Λ −2 ) in Eq. (20).…”

“…At the same time, some of the puzzles in the SM, such as neutrino mass generation and dark matter, have stimulated the scientific community to consider models with a larger scalar sector [4][5][6][7][8][9][10][11][12][13][14][15][16]. Extended scalar sector are also predicted by models like supersymmetry [17][18][19], some versions of strong electroweak symmetry breaking models [20] and nonminimal composite Higgs models [21][22][23]. Although no deviation from the SM has yet been observed, the LHCb collaboration has reported anomalies in the Lepton Flavour Universality violating ratios, R K and R K * .…”
