Measurement of Λ (1520) production in pp collisions at √s=7TeV and p–Pb collisions at √sNN=5.02TeV [PDF]

open access: yes, 2020
The production of the Λ (1520) baryonic resonance has been measured at midrapidity in inelastic pp collisions at s=7TeV and in p–Pb collisions at sNN=5.02TeV for non-single diffractive events and in multiplicity classes.

Search for a heavy resonance decaying to a pair of vector bosons in the lepton plus merged jet final state at s=13$$ \sqrt{s}=13 $$ TeV [PDF]

open access: yes, 2018
A bstractA search for a new heavy particle decaying to a pair of vector bosons (WW or WZ) is presented using data from the CMS detector corresponding to an integrated luminosity of 35.9 fb−1 collected in proton-proton collisions at a centre-of-mass ...

Search for boosted low-mass resonances decaying into hadrons produced in association with a photon in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
Many extensions of the Standard Model, including those with dark matter particles, propose new mediator particles that decay into hadrons. This paper presents a search for such low mass narrow resonances decaying into hadrons using 140 fb −1 of proton ...

On Features and Nongaussianity from Inflationary Particle Production

open access: yes, 2010
Interactions between the inflaton and any additional fields can lead to isolated bursts of particle production during inflation (for example from parametric resonance or a phase transition).

On a possible large width 750 GeV diphoton resonance at ATLAS and CMS [PDF]

open access: yes, 2015
A bstractThe ATLAS and CMS experiments at the LHC have reported an excess of diphoton events with invariant mass around 750 GeV, with local significance of about 3.6 σ and 2.6 σ, respectively.

Kinematic surprises in twisted-particle collisions [PDF]

open access: yesPhysical Review D, 2019
“Twisted particles” refer to non-plane-wave states of photons, electrons, hadrons, or any other particles which carry nonzero, adjustable orbital angular momentum with respect to their average propagation direction.

Search for heavy resonances in final states with four leptons and missing transverse momentum or jets in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
A search for a new heavy boson produced via gluon-fusion in the four-lepton channel with missing transverse momentum or jets is performed. The search uses proton-proton collision data equivalent to an integrated luminosity of 139 fb −1 at a centre-of ...

Resonances as Probes of Heavy-Ion Collisions at ALICE

open access: yes, 2015
Hadronic resonances serve as unique probes in the study of the hot and dense nuclear matter produced in heavy-ion collisions. Properties of the hadronic phase of the collision can be extracted from measurements of the suppression of resonance yields.

Investigating strangeness enhancement with multiplicity in pp collisions using angular correlations

open access: yesJournal of High Energy Physics
A study of strange hadron production associated with hard scattering processes and with the underlying event is conducted to investigate the origin of the enhanced production of strange hadrons in small collision systems characterised by large charged ...

Diquark resonance and single top production at the Large Hadron Collider [PDF]

open access: yes, 2012
New physics at the TeV scale is highly anticipated at the LHC. New particles with color, if within the LHC energy reach, will be copiously produced. One such particle is a diquark, having the quantum numbers of two quarks, and can be a scalar or a vector.
