Partially composite dark matter

Abstract

In a class of theories where the Higgs field emerges as a pseudo NambuGoldstone boson, it is often assumed that interactions to generate the top Yukawa coupling provide the Higgs potential as well. Such a scenario generically requires a little cancellation in the leading contribution to the Higgs potential, and the electroweak scale is generated by the balance between the leading and the subleading contributions. We, instead, consider the possibility that the contribution from the dark matter particle balances against that from the top quark. The thermal relic of the new particle explains the abundance of dark matter in a consistent region of the parameter space, and the direct detection is found to be promising.

Accidental composite dark matter

“…with supersymmetry [5], with composite [6][7][8][9] or partially composite Higgs [10][11][12], with a mirror-SM sector [13] or quirks [14] or a fourth generation [15] as well as from a phenomenological point of view, in order to realise special situations (such as inelastic DM, asymmetric DM, strongly interacting DM, magnetic DM, etc.) often motivated by anomalies [16][17][18][19][20].…”

LHC signatures of neutral pseudo-Goldstone boson in the E 6CHM

“…anarchic matrices, adequate suppression of flavour changing neutral currents can be obtained only if f is larger than 10 TeV [13,14,16,17,20] 5 . The implications of the composite Higgs models were also studied for Higgs physics [10,11,[23][24][25][26], gauge coupling unification [27,28], dark matter [8,24,28,29] and collider phenomenology [9,10,12,16,19,26,30]. Non-minimal composite Higgs models were considered in [8,23,24,28,29,31].…”
