Phenomenology of electroweak portal dark showers: high energy direct probes and low energy complementarity by Hsin-Chia Cheng, Xu-Hui Jiang, Lingfeng Li

“…The portal interactions allow SM bosons, such as Z and h, or additional bosons that mix with them, to decay into dark quarks, producing dark showers. The light dark mesons are expected to be long-lived particles (LLPs), as their decays back to the SM states through the EW-portal interactions typically have macroscopic decay lengths. …”

Proposal to use LHC general-purpose detectors in “beam-dump” measurements for long-lived particles by Bhaskar Dutta, Doojin Kim, Hyunyong Kim

“…This analysis can be extended to investigate various types of light mediators with couplings to the Standard Model leptons and quarks.…”

A New Method for Measuring Higgs Mass by Berger Thomas, Tian Junping

“…The new method employs the signal channel of Higgs decaying to a pair of fermions, in particular τ leptons, or 2 quarks bb¯ and makes use of transverse momentum conservations alone instead of the 4-momentum conservation in the recoil mass method. …”

Inflation models with Peccei–Quinn symmetry and axion kinetic misalignment by Hyun Min Lee, Adriana G. Menkara, Myeong-Jung Seong, Jun-Ho Song

“…In the DFSZ type scenarios for the axion, we obtain the PQ anomalies from the Standard Model quarks carrying nonzero PQ charges in some of two Higgs doublet models, solving the strong CP problem by the QCD potential for the axion. …”

Triple (and quadruple) soft-gluon radiation in QCD hard scattering by Stefano Catani, Dimitri Colferai, Alessandro Torrini

“…Considering triple soft-gluon radiation from three hard partons, colour quadrupole interactions break the Casimir scaling symmetry between quarks and gluons. We also present some results on the radiation of four soft gluons from two hard partons, and we discuss the colour monster contribution and its relation with the violation (and generalization) of Casimir scaling. …”
