Axion-like particle at the 10 GeV scale: Higgs decays to wide jets and photons

Bogdan A. Dobrescu, Subhojit Roy

If axion-like particles (ALPs) exist, they may have renormalizable couplings only to the Higgs boson ( $h^{0}$ ) or to fields beyond the Standard Model. An ALP $A_{h}$ lighter than about…

Diophantine equations with sum of cubes and cube of sum

Bogdan A. Dobrescu, Patrick J. Fox

We solve Diophantine equations of the type $a (x^{3} + y^{3} + z^{3}) = (x + y + z)^{3}$ , where $x, y, z$ are integer variables, and the coefficient $a \neq = 0$ is r…

TeV-scale particles and LHC events with dijet pairs

Bogdan A. Dobrescu

Scalar particles that couple to two up quarks may be produced at the LHC even if they are ultraheavy, in the $8 - 10$ TeV mass range. A renormalizable theory that includes a diquark…
