A generalised-$k_t$ jet algorithm for Deep Inelastic Scattering / van Beekveld, Melissa (NIKHEF, Amsterdam) ; Ferrario Ravasio, Silvia (Turin U.) ; Karlberg, Alexander (Oxford U., Theor. Phys. ; CERN) ; Peake, Darcy (Sussex U.)
We introduce an inclusive generalised-$k_t$ jet algorithm for Deep Inelastic Scattering, defined in the Breit frame and implemented in fjcontrib. [...]

How traversable is a traversable wormhole? / Freivogel, Ben (U. Amsterdam, GRAPPA) ; Fumagalli, Alessandro (U. Amsterdam, GRAPPA) ; Tomašević, Marija (CERN)
To answer the above question, we study low-frequency scattering in the four-dimensional traversable wormhole of Maldacena, Milekhin, and Popov. [...]

Constraining the real scalar singlet extension of the SM / Bosse, Moritz (Dortmund U.) ; Hiller, Gudrun (Dortmund U. ; CERN) ; Litim, Daniel (Sussex U.) ; Maltoni, Fabio (CERN ; Louvain U., CP3 ; Bologna U.) ; Ramsey-Musolf, Michael J. (Tsung-Dao Lee Inst., Shanghai ; Shanghai Jiao Tong U. ; Shanghai Jiaotong U. ; Caltech) ; Tentori, Simone (Louvain U., CP3) ; Xia, Guotao (Tsung-Dao Lee Inst., Shanghai ; Shanghai Jiao Tong U. ; Shanghai Jiaotong U.)
The real scalar singlet extension of the standard model provides a minimal framework in which the Higgs sector can realise a strong first-order electroweak phase transition and improve the stability of the electroweak vacuum. [...]

CMB Constraints on Pre-Inflationary Axion Dark Matter Isocurvature / Petretti, Catherine (Harvard-Smithsonian Ctr. Astrophys. ; MIT) ; Singh, Praniti (Brown U. (main)) ; Braglia, Matteo (CERN) ; Chen, Xingang (Harvard-Smithsonian Ctr. Astrophys. ; MIT) ; Fan, JiJi (Brown U. (main) ; Brown U.) ; Li, Lingfeng (Nanjing Normal U. ; ICTP-AP, Beijing)
Although measurements of the Cosmic Microwave Background (CMB) are consistent with a nearly scale-invariant primordial spectrum of adiabatic perturbations, in which the energy densities of different components (radiation, baryons, and dark matter) fluctuate proportionally, there could also exist isocurvature perturbations, in which density fluctuations of the individual components differ from the adiabatic mode.

Search for single production of a vector-like $ {\mathrm{B}}^{\prime}$ quark decaying to a top quark and a W boson in the single-lepton final state in proton-proton collisions at $ \sqrt{s}= $ 13 TeV
A search is presented for the single production of a narrow-width vector-like $ {\mathrm{B}}^{\prime}$ quark that decays to a t quark and a W boson, with one of the decay products yielding an electron or muon. [...]

Dependence of two-particle azimuthal correlations on the forward rapidity gap width in $ \mathrm{p}\text{Pb} $ collisions at $ \sqrt{\smash[b]{s_{_{\mathrm{NN}}}}} = $ 8.16 TeV
One of the most striking features of relativistic heavy ion collisions is the presence of collective flow of thousands of produced particles. [...]

Probing Nucleon Spin Structure with a Polarized Gamma Beam from Compton Backscattering at FCC-ee / Canbay, A C (Ankara U.) ; Sultansoy, S (TOBB ETU, Ankara) ; Zimmermann, F (CERN)
We present a kinematic and optical design of a high-energy polarized gamma-ray facility based on Compton backscattering of lasers against the FCC-ee electron beams in its $Z$, $WW$, $ZH$ and $t\bar{t}$ modes. [...]
