Lund multiplicity in QCD jets
Rok Medves, Alba Soto-Ontoso, Gregory Soyez
We compute the average Lund multiplicity of high-energy QCD jets. This extends an earlier calculation, done for event-wide multiplicity in collisions [arxiv:2205.02861], t…
Light Axiodilatons: Matter Couplings, Weak-Scale Completions and Long-Distance Tests of Gravity
Philippe Brax, Cliff Burgess, Fernando Quevedo
We consider the physical implications of very light axiodilatons motivated by a novel mechanism to substantially reduce the vacuum energy proposed in arXiv:2110.10352. We address t…
Polarization phenomena in the reaction in frame of the non-resonant mechanism
G. I. Gakh, M. I. Konchatnij, N. P. Merenkov +1
The dependence of the nucleon polarization in the reaction over different invariant variables in frame of the non-resonant mechanism, has been der…
Dihadron production in DIS at NLO: the real corrections
Edmond Iancu, Yair Mulian
By using the formalism of the light-cone wave function along with the colour glass condensate effective theory, we consider next-to-leading order (NLO) corrections to the productio…
Sifting composite from elementary models at FCCee and CePC
G. Cacciapaglia, A. Deandrea, A. M. Iyer +1
New Physics models with either an elementary or composite origin are often associated with a similar imprint in a direct search at colliders, case in point being the production of…
Universal Decomposition of Phase-Space Integrands
David A. Kosower, Ben Page
One-loop integrands can be written in terms of a simple, process-independent basis. We show that a similar basis exists for integrands of phase-space integrals for the real-emissio…
Pushing forward jet substructure measurements in heavy-ion collisions
Daniel Pablos, Alba Soto-Ontoso
Energetic jets that traverse the quark-gluon plasma created in heavy-ion collisions serve as excellent probes to study this new state of deconfined QCD matter. Presently, however,…
Medium-enhanced radiation
Maximilian Attems, Jasmine Brewer, Gian Michele Innocenti +5
We show that the same QCD formalism that accounts for the suppression of high- hadron and jet spectra in heavy-ion collisions predicts medium-enhanced production of …
Fixed-target charmonium production and pion parton distributions
Wen-Chen Chang, Jen-Chieh Peng, Stephane Platchkov +1
We investigate how charmonium hadroproduction at fixed-target energies can be used to constrain the gluon distribution in pions. Using nonrelativistic QCD (NRQCD) formulation, the…
Constraining Non-Standard Interactions with Coherent Elastic Neutrino-Nucleus Scattering at the European Spallation Source
Sabya Sachi Chatterjee, Stéphane Lavignac, O. G. Miranda +1
The European Spallation Source (ESS), currently under construction in Sweden, will provide an intense pulsed neutrino flux allowing for high-statistics measurements of coherent ela…
An introductory lecture on Generalised Parton Distributions
Cédric Mezrag
These lecture notes on Generalised Parton Distributions aim at providing a general picture of the field on the theoretical and phenomenological sides to master and Ph.D. students.…
Matching generalised transverse-momentum-dependent distributions onto generalised parton distributions at one loop
Valerio Bertone
The operator definition of generalised transverse-momentum-dependent (GTMD) distributions is exploited to compute for the first time the full set of one-loop corrections to the off…
PanScales showers for hadron collisions: all-order validation
Melissa van Beekveld, Silvia Ferrario Ravasio, Keith Hamilton +4
We carry out extensive tests of the next-to-leading logarithmic (NLL) accuracy of the PanScales parton showers, as introduced recently for colour-singlet production in hadron colli…
A Unitarity Approach to Two-Loop All-Plus Rational Terms
David A. Kosower, Sebastian Pögel
We present a calculation of the rational terms in two-loop all-plus gluon amplitudes using -dimensional unitarity. We use a conjecture of separability of the two loops, and then…
Unpolarized Transverse Momentum Distributions from a global fit of Drell-Yan and Semi-Inclusive Deep-Inelastic Scattering data
Alessandro Bacchetta, Valerio Bertone, Chiara Bissolotti +5
We present an extraction of unpolarized transverse-momentum-dependent parton distribution and fragmentation functions based on more than two thousands data points from several expe…
Revisiting evolution equations for generalised parton distributions
Valerio Bertone, Hervé Dutrieux, Cédric Mezrag +2
We revisit the evolution of generalised parton distributions (GPDs) in momentum space. We formulate the evolution kernels at one-loop in perturbative QCD (pQCD) in a form suitable…
-Anomalous Interactions of the Holographic Dilaton
Csaba Csaki, Jay Hubisz, Ameen Ismail +2
We explore higher-derivative terms in the low-energy effective action for the dilaton, the Goldstone boson of spontaneously broken scale invariance. Focusing on the simplest hologr…
EpIC: novel Monte Carlo generator for exclusive processes
E. C. Aschenauer, V. Batozskaya, S. Fazio +6
We present the EpIC Monte Carlo event generator for exclusive processes sensitive to generalised parton distributions. EpIC utilises the PARTONS framework, which provides a flexibl…
On the origin of the reactor antineutrino anomalies in light of a new summation model with parameterized transitions
A. Letourneau, V. Savu, D. Lhuillier +7
We investigate the possible origins of the norm and shape reactor antineutrino anomalies in the framework of a summation model (SM) where transitions are simulated by a phe…
Lund and Cambridge multiplicities for precision physics
Rok Medves, Alba Soto-Ontoso, Gregory Soyez
We revisit the calculation of the average jet multiplicity in high-energy collisions. First, we introduce a new definition of (sub)jet multiplicity based on Lund declusterings obta…
PanScales parton showers for hadron collisions: formulation and fixed-order studies
Melissa van Beekveld, Silvia Ferrario Ravasio, Gavin P. Salam +3
We formulate PanScales parton showers for hadron collisions so as to achieve next-to-leading logarithmic (NLL) accuracy across a broad set of observables. We do so specifically for…
Pion and kaon fragmentation functions at next-to-next-to-leading order
Rabah Abdul Khalek, Valerio Bertone, Alice Khoudli +1
We present a new determination of unpolarised charged pion and kaon fragmentation functions from a set of single-inclusive electron-positron annihilation and lepton-nucleon semi-in…
The PDF4LHC21 combination of global PDF fits for the LHC Run III
Richard D. Ball, Jon Butterworth, Amanda M. Cooper-Sarkar +19
A precise knowledge of the quark and gluon structure of the proton, encoded by the parton distribution functions (PDFs), is of paramount importance for the interpretation of high-e…
Coherent elastic neutrino-nucleus scattering: Terrestrial and astrophysical applications
M. Abdullah, H. Abele, D. Akimov +272
Coherent elastic neutrino-nucleus scattering (CENS) is a process in which neutrinos scatter on a nucleus which acts as a single particle. Though the total cross section is large…
