Exclusion Limits on a Scalar Decaying to Photons and Distinguishing Its Production Mechanisms
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 LHC run‐II has a great potential to search for new resonances in the diphoton channel. Latest 13 TeV data already put stringent limits on the cross sections in the diphoton channel assuming the resonance is produced through the gluon‐gluon fusion. Many beyond the Standard Model (SM) theories predict TeV‐scale scalars, which copiously decay to diphotons.

Parton-shower effects in electroweak WZjj production at the next-to-leading order of QCD
European Physical Journal C: Particles and Fields, 2019 We present an implementation of $$WZjj$$ WZjj production via vector-boson fusion in the POWHEG BOX, a public tool for the matching of next-to-leading order QCD calculations with multi-purpose parton-shower generators.

PanScales showers for hadron collisions: all-order validation
Journal of High Energy Physics, 2022 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 collisions.

A Heavy Scalar at the LHC from Vector‐Boson Fusion
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 A hypothetical scalar mixed with the standard model Higgs appears in few contexts of new physics. This study addresses the question what mass range is in the reach of 14 TeV LHC given different magnitudes of mixing angle α, where event simulations are based on production from vector‐boson fusion channel and decays into SM leptons through WW or ZZ.

Acta Physica Polonica B Proceedings SupplementThe consistent combination of Next-to-Leading-Order (NLO) perturbative QCD with the logarithmic resummation of parton shower algorithms (‘NLO matching’) is a workhorse of precision QCD in the LHC era. Two methods for achieving this have been widely adopted: Mc@Nlo and Powheg. The differences between them are formally Next-to-Next-to-Leading-Order (NNLO)

Searching for the Minimal Seesaw Models at the LHC and Beyond
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 The existence of the tiny neutrino mass and the flavor mixing can be naturally explained by type I Seesaw model which is probably the simplest extension of the Standard Model (SM) using Majorana type SM gauge singlet heavy Right Handed Neutrinos (RHNs).
