Tagging the Higgs boson decay to bottom quarks with colour-sensitive observables and the Lund jet plane

Luca Cavallini, Andrea Coccaro, Charanjit K. Khosa +6

We study the problem of distinguishing $b$ -jets stemming from the decay of a colour singlet, such as the Higgs boson, from those originating from the abundant QCD background. In pa…

Phenomenology of jet angularities at the LHC

Daniel Reichelt, Simone Caletti, Oleh Fedkevych +3

We compute resummed and matched predictions for jet angularities in hadronic dijet and Z+jet events with and without grooming the candidate jets using the SoftDrop technique. Our t…

Probing B-Anomalies via Dimuon Tails at a Future Collider

Bradley Garland, Sebastian Jäger, Charanjit K. Khosa +1

We investigate the sensitivity of future proton-proton colliders to a contact interaction of the form $1/ Λ^{2} (b ˉ_{L} γ_{μ} s_{L}) (μ ˉ_{L} γ^{μ} μ_{L})$ as indicated by the long-standing r…

Constraining new physics with SModelS version 2

Gaël Alguero, Jan Heisig, Charanjit Khosa +6

We present version 2 of SModelS, a program package for the fast reinterpretation of LHC searches for new physics on the basis of simplified model results. The major novelty of the…

The new $P_{cs} (4459)$ , $Z_{cs} (3985)$ , $Z_{cs} (4000)$ and $Z_{cs} (4220)$ and the possible emergence of flavor pentaquark octets and tetraquark nonets

J. Ferretti, E. Santopinto

Our hadro-charmonium and compact tetraquark model predictions, published before the BESIII and LHCb experimental data for the $Z_{cs} (3985)$ and $Z_{cs} (4003)$ tetraquarks…

Tagging the initial-state gluon

Simone Caletti, Oleh Fedkevych, Simone Marzani +1

We study the production of an electroweak boson in association with jets, in processes where the jet with the highest transverse momentum is identified as quark-initiated. The quar…

Publishing statistical models: Getting the most out of particle physics experiments

Kyle Cranmer, Sabine Kraml, Harrison B. Prosper +30

The statistical models used to derive the results of experimental analyses are of incredible scientific value and are essential information for analysis preservation and reuse. In…

Triply-heavy tetraquarks in an extended relativized quark model

Qi-Fang Lü, Dian-Yong Chen, Yu-Bing Dong +1

In this paper, we adopt an extended relativized quark model to investigate the triply-heavy tetrquarks systematically. The mass spectra are obtained by solving the four-body relati…

The role of colour flows in matrix element computations and Monte Carlo simulations

Stefano Frixione, Bryan R. Webber

We discuss how colour flows can be used to simplify the computation of matrix elements, and in the context of parton shower Monte Carlos with accuracy beyond leading-colour. We sho…

Threshold resummation of transverse momentum distributions beyond next-to-leading log

Stefano Forte, Giovanni Ridolfi, Simone Rota

We derive a general expression for the threshold resummation of transverse momentum distributions for processes with a colorless final state, by suitably generalizing the renormali…

On factorisation schemes for the electron parton distribution functions in QED

Stefano Frixione

The electron, positron, and photon Parton Distribution Functions (PDFs) of the unpolarised electron have recently been computed at the next-to-leading logarithmic accuracy in QED,…

Higgs boson tagging with the Lund jet plane

Charanjit K. Khosa, Simone Marzani

We construct a procedure to separate boosted Higgs bosons decaying into hadrons, from the background due to strong interactions. We employ the Lund jet plane to obtain a theoretica…

Quark structure of the $X (4500)$ , $X (4700)$ and $χ_{c} (4 P, 5 P)$ states

J. Ferretti, E. Santopinto

We study some of the main properties (masses and open-flavor strong decay widths) of $4 P$ and $5 P$ charmonia. While there are two candidates for the $χ_{c0} (4 P, 5 P)$ states, the…

Jet Angularities in Z+jet production at the LHC

Simone Caletti, Oleh Fedkevych, Simone Marzani +4

We present a phenomenological study of angularities measured on the highest transverse-momentum jet in LHC events that feature the associate production of a $Z$ boson and one or mo…

Fully Geant4 compatible package for the simulation of Dark Matter in fixed target experiments

M. Bondi, A. Celentano, R. R. Dusaev +5

We present the package for the simulation of DM (Dark Matter) particles in fixed target experiments. The most convenient way of this simulation (and the only possible way in the ca…
