Dark photon decay beyond the Euler-Heisenberg limit


Author(s): Samuel D. McDermott, Hiren H. Patel, and Harikrishnan Ramani

We calculate the exact width for a dark photon decaying to three photons at one-loop order for dark photon masses ${m}^{′}$ below the ${e}^{+}{e}^{−}$ production threshold of $2{m}_{e}$. We find substantial deviations from previous results derived from the lowest order Euler-Heisenberg effective Lag...

NNLO QCD corrections to associated $WH$ production and $H→b\overline{b}$ decay


Author(s): Fabrizio Caola, Gionata Luisoni, Kirill Melnikov, and Raoul Röntsch

We present a computation of the next-to-next-to-leading-order (NNLO) QCD corrections to the production of a Higgs boson in association with a $W$ boson at the LHC and the subsequent decay of the Higgs boson into a $b\overline{b}$ pair, treating the $b$ quarks as massless.

Twist-3 contributions to wide-angle photoproduction of pions


Author(s): P. Kroll and K. Passek-Kumerički

We investigate wide-angle ${π}^{0}$ photoproduction within the handbag approach to twist-3 accuracy. In contrast to earlier work both the 2-particle as well as the 3-particle twist-3 contributions are taken into account. It is shown that both are needed for consistent results that respect gauge inva...

Cosmological bounds on non-Abelian dark forces

Non-Abelian dark gauge forces that do not couple directly to ordinary matter may be realized in nature. The minimal form of such a dark force is a pure Yang-Mills theory. If the dark sector is reheated in the early Universe, it will be realized as a set of dark gluons at high temperatures and as a c...

Lepton-number-charged scalars and neutrino beamstrahlung

Experimentally, baryon number minus lepton number, $B−L$, appears to be a good global symmetry of nature. We explore the consequences of the existence of gauge-singlet scalar fields charged under $B−L$–dubbed lepton-number-charged scalars (LeNCSs)—and postulate that these couple to the standard mode...

Author(s): Ying-nan Mao

We propose spontaneous $CP$ violation in the simplest little Higgs model. In this model, the pseudoscalar field can acquire a nonzero vacuum expectation value. This leads to a mixing between the two scalars with different $CP$ charge, which means that spontaneous $CP$ violation occurs. It is also a ...

Recent results from the Pierre Auger Collaboration have shown that the composition of ultrahigh-energy cosmic rays (UHECRs) becomes gradually heavier with increasing energy.

Cosmological $α$-attractors are observationally favored due to the asymptotic flatness of the potential. Since its flatness induces the negative pressure, the coherent oscillation of the inflaton field could fragment into quasistable localized objects called I-balls (or “oscillons”). We investigated...

Tachyon constant-roll inflation


Author(s): A. Mohammadi, Kh. Saaidi, and T. Golanbari

The constant-roll inflation is studied where the inflaton is taken as a tachyon field. Based on this approach, the second slow-roll parameter is taken as a constant which leads to a differential equation for the Hubble parameter. Finding an exact solution for the Hubble parameter is difficult and le...
