Combining single and double parton scatterings in a parton shower [PDF]

Journal of High Energy Physics, 2020
Abstract Double parton scattering (DPS) processes in which there is a perturbative “1 → 2” splitting in both protons overlap with loop corrections to single parton scattering (SPS). Any fundamental theoretical treatment of DPS needs to address this double-counting issue.

Slepton pair production in the POWHEG BOX

, 2012
We present an implementation for slepton pair production at hadron colliders in the POWHEG BOX, a framework for combining next-to-leading order QCD calculations with parton-shower Monte-Carlo programs.

QED Radiative Correction for the Single-W Production using a Parton Shower Method [PDF]

, 2000
A parton shower method for the photonic radiative correction is applied to the single W-boson production processes. The energy scale for the evolution of the parton shower is determined so that the correct soft-photon emission is reproduced.

Fate of N additions in a multiple resource‐limited Mediterranean oak savanna

Ecosphere, Volume 10, Issue 11, November 2019., 2019
Abstract Mediterranean oak savannas, such as Spanish dehesas, are multiple resource‐limited ecosystems found in semiarid regions which are key contributors to interannual variability of the global carbon (C) budget. Interactions between nitrogen (N) and phosphorus (P) cycles are expected to play a major role in overall ecosystem function as ...

Effects of subleading color in a parton shower [PDF]

, 2015
Parton shower Monte Carlo event generators in which the shower evolves from hard splittings to soft splittings generally use the leading color (LC) approximation, which is the leading term in an expansion in powers of $1/N_\Lc^2$, where $N_\Lc = 3$ is ...

Modification of Jet Structure in High‐Multiplicity pp Collisions due to Multiple‐Parton Interactions and Observing a Multiplicity‐Independent Characteristic Jet Size

Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019
We study the multiplicity dependence of jet structures in pp collisions using Monte Carlo event generators. We give predictions for multiplicity‐differential jet structures and present evidence for a nontrivial jet shape dependence on charged hadron event multiplicity that can be used as a sensitive tool to experimentally differentiate between equally ...

Constraints on Higgs Effective Couplings in Hνν¯ Production of CLIC at 380 GeV

Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018
The potential of the e+e-→νν¯H process in the first stage of CLIC considering center‐of‐mass energy of 380 GeV and assuming the baseline integrated luminosity of 500 fb -1 is examined to probe CP‐conserving dimension‐six operators in a model‐independent Standard Model effective field theory framework. In the analysis, a detailed fast simulation on e+e-→

Jet vetoing and Herwig++

, 2011
We investigate the simulation of events with gaps between jets with a veto on additional radiation in the gap in Herwig++. We discover that the currently-used random treatment of radiation in the parton shower is generating some unphysical behaviour for ...

NLO corrections in the initial-state parton shower Monte Carlo [PDF]

, 2013
The decade-old technique of combining NLO-corrected hard process with LO-level parton shower Monte Carlo is now mature and used in practice of the QCD calculations in the LHC data analysis.

Searches for Massive Graviton Resonances at the LHC

Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018
The Standard Model problems lead to the new theories of extra dimensions: Randall‐Sundrum model, Arkani‐Hamed‐Dimopoulos‐Dvali model, and TeV−1 model. In the framework of these models, with the help of computer program Pythia8.2, the production cross sections for Kaluza‐Klein particles at various energies at the LHC were calculated.
