Parametrizations of the Spin Density Matrix
Elvio Di Salvo, Ziad Jean Ajaltouni
We propose for the spin density matrix two parametrizations which automatically fulfil the non-negativity conditions, without setting any bound on the parameters. The first one rel…
May the four be with you: Novel IR-subtraction methods to tackle NNLO calculations
W. J. Torres Bobadilla, G. F. R. Sborlini, P. Banerjee +21
In this report, we present a discussion about different frameworks to perform precise higher-order computations for high-energy physics. These approaches implement novel strategies…
Model-independent approach for incorporating interference effects in collider searches for new resonances
Stefano Frixione, Lydia Roos, Edmund Ting +3
The presence of large-mass resonances in the data collected at the Large Hadron Collider would provide direct evidence of physics beyond the Standard Model. A key challenge in curr…
Double parton scattering in four-jet production in proton-proton collisions at the LHC
Oleh Fedkevych, Anna Kulesza
We study the contribution from double parton scattering (DPS) to four-jet production at the LHC, both at the leading order accuracy and after incorporating the effects of QCD radia…
XYZ spectroscopy at electron-hadron facilities: Exclusive processes
JPAC Collaboration, M. Albaladejo, A. N. Hiller Blin +5
The next generation of electron-hadron facilities has the potential for significantly improving our understanding of exotic hadrons. The XYZ states have not been seen in photon-ind…
Towards Machine Learning Analytics for Jet Substructure
Gregor Kasieczka, Simone Marzani, Gregory Soyez +1
The past few years have seen a rapid development of machine-learning algorithms. While surely augmenting performance, these complex tools are often treated as black-boxes and may i…
Exclusive tensor meson photoproduction
JPAC Collaboration, V. Mathieu, A. Pilloni +5
We study tensor meson photoproduction outside of the resonance region, at beam energies of few GeVs. We build a model based on Regge theory that includes the leading vector and axi…
Heavy Hybrid Decays in a Constituent Gluon Model
Christian Farina, Hugo Garcia Tecocoatzi, Alessandro Giachino +2
A constituent gluon model that is informed by recent lattice field theory is developed. The model is then used to compute hybrid strong decay widths, that can be useful for the Glu…
The nature of from high-multiplicity collisions
Angelo Esposito, Elena G. Ferreiro, Alessandro Pilloni +2
The structure of exotic resonances that do not trivially fit the usual quark model expectations has been a matter of intense scientific debate during the last two decades. A possib…
A study of tetraquark decays in 4 muons and in at LHC
C. Becchi, A. Giachino, L. Maiani +1
We perform a quantitative analysis of the decays of tetraquarks with into 4 muons and into hidden- and open-charm mesons and estimate, for…
New production channels for light dark matter in hadronic showers
Andrea Celentano, Luc Darmé, Luca Marsicano +1
Hadronic showers transfer a relevant amount of their energy to electromagnetic subshowers. We show that the generation of "secondary" dark photons in these sub-showers is significa…
Precise predictions for boosted Higgs production
K. Becker, F. Caola, A. Massironi +20
Inclusive Higgs boson production at large transverse momentum is induced by different production channels. We focus on the leading production through gluon fusion, and perform a co…
Challenges in Monte Carlo event generator software for High-Luminosity LHC
The HSF Physics Event Generator WG, :, Andrea Valassi +38
We review the main software and computing challenges for the Monte Carlo physics event generators used by the LHC experiments, in view of the High-Luminosity LHC (HL-LHC) physics p…
Search for tetraquark decays in 4 muons, , and channels at LHC
C. Becchi, A. Giachino, L. Maiani +1
We perform a quantitative analysis of the tetraquark decays into hidden- and open-bottom mesons and calculate, for the first time, the tetraqu…
On the reduction of negative weights in MC@NLO-type matching procedures
R. Frederix, S. Frixione, S. Prestel +1
We show how a careful analysis of the behaviour of a parton shower Monte Carlo in the vicinity of the soft and collinear regions allows one to formulate a modified MC@NLO-matching…
Quark structure of the and resonances and their strong and radiative decays
J. Ferretti, E. Santopinto, M. Naeem Anwar +1
We calculate the masses of states with threshold corrections in a coupled-channel model. The model was recently applied to the description of the properties of $χ_{…
Bottomonium spectrum with a Dirac potential model in the momentum space
David Molina, Maurizio De Sanctis, Cesar Fernández-Ramírez +1
We study the bottomonium spectrum using a relativistic potential model in the momentum space. This model is based on a complete one gluon exchange interaction with a momentum depen…
Hidden-charm and bottom tetra- and pentaquarks with strangeness in the hadro-quarkonium and compact tetraquark models
J. Ferretti, E. Santopinto
In two recent papers, we used the hadro-quarkonium model to study the properties of hidden-charm and bottom tetraquarks and pentaquarks. Here, we extend the previous results and ca…
