Criticality in the scale invariant standard model (squared)

Autor: Robert Foot, Archil Kobakhidze, Alexander Spencer-Smith

Publikováno v: Physics Letters B, Vol 747, Iss C, Pp 169-172 (2015)

We consider first the standard model Lagrangian with μh2 Higgs potential term set to zero. We point out that this classically scale invariant theory potentially exhibits radiative electroweak/scale symmetry breaking with very high vacuum expectation

Chiral SU(4) explanation of the

b \to s

anomalies

Autor: Shyam Balaji, Michael A. Schmidt, Robert Foot

Publikováno v: Physical Review

We propose a variant of the Pati-Salam model, with gauge group SU(4)C×SU(2)L×U(1)Y′, in which the chiral left-handed quarks and leptons are unified into a 4_ of SU(4)C, while the right-handed quarks and leptons have quite a distinct treatment. Th

Diurnal modulation signal from dissipative hidden sector dark matter

Autor: Robert Foot, Sunny Vagnozzi

Physics Letters B, Vol 748, Iss C, Pp 61-66 (2015)

We consider a simple generic dissipative dark matter model: a hidden sector featuring two dark matter particles charged under an unbroken $U(1)'$ interaction. Previous work has shown that such a model has the potential to explain dark matter phenomen

Observations indicate that ordinary matter, the baryons, influence the structural properties of dark matter on galactic scales. One such indication is the radial acceleration relation, which is a tight correlation between the measured gravitational a

Explaining the 750 GeV diphoton excess with a colored scalar charged under a new confining gauge interaction

Autor: Robert Foot, John Gargalionis

Publikováno v: Physical Review D. 94

We consider a charged scalar particle $\chi$ of mass around 375 GeV charged under both $SU(3)_c$ and a new confining non-abelian gauge interaction. After pair production, these interactions confine the exotic scalar into non-relativistic bound states

Mirror dark matter will be confirmed or excluded by XENON1T

Autor: Jackson D. Clarke, Robert Foot

Publikováno v: Physics Letters B
Physics Letters B, Vol 766, Iss C, Pp 29-34 (2017)

Mirror dark matter, where dark matter resides in a hidden sector exactly isomorphic to the standard model, can be probed via direct detection experiments by both nuclear and electron recoils if the kinetic mixing interaction exists. In fact, the kine

Solving the small-scale structure puzzles with dissipative dark matter

Autor: Robert Foot, Sunny Vagnozzi

Small-scale structure is studied in the context of dissipative dark matter, arising for instance in models with a hidden unbroken Abelian sector, so that dark matter couples to a massless dark photon. The dark sector interacts with ordinary matter vi
