open access: yes, 2006
The production of tau leptons in ep collisions is investigated using data recorded by the H1 detector at HERA in the period 1994-2000. Tau leptons are identified by detecting their decay products, using leptonic and hadronic decay modes.

Nonsinglet structure function of the (3)He-(3)H system and divergence of the Gottfried integral [PDF]

open access: yes, 2001
We study shadowing and antishadowing corrections to the flavor nonsinglet structure function F₂³He-F₂³H and show that the difference between the one-particle density distributions of ³He and ³H plays an important role at very small x.

Dijet asymmetry in the resummation improved perturbative QCD approach

open access: yesPhysics Letters B, 2018
We develop the first systematic theoretical approach to dijet asymmetries in hadron–hadron collisions based on the perturbative QCD (pQCD) expansion and the Sudakov resummation formalism.

LEPTON NUMBER AND LEPTON FLAVOR VIOLATIONS IN SEESAW MODELS [PDF]

open access: yesModern Physics Letters A, 2002
We discuss the impact of fermion mass matrices on some lepton number violating processes, namely baryogenesis via leptogenesis and neutrinoless double beta decay, and on some lepton flavor violating processes, namely radiative lepton decays in supersymmetric seesaw models.

Lepton-Jet Background [PDF]

open access: yes, 2021
We analyzed the contribution of potential backgrounds for lepton-jets created from the decay of dark photons. Lepton-jets are identified by the presence of at least two collimated leptons, but these jets may have significant pion contamination. Therefore,

Probing transverse momentum broadening via dihadron and hadron-jet angular correlations in relativistic heavy-ion collisions

open access: yesPhysics Letters B, 2017
Dijet, dihadron, hadron-jet angular correlations have been reckoned as important probes of the transverse momentum broadening effects in relativistic nuclear collisions.

Study of the ZZ diboson production at CDF II [PDF]

open access: yes, 2013
The subject of this Thesis is the production of a pair of massive Z vector bosons in the proton antiproton collisions at the Tevatron, at the center-of-mass energy sqrt(s) = 1.96 TeV.

Nuclear suppression of the $$\phi $$ ϕ meson yields with large $$p_T$$ p T at the RHIC and the LHC

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
We calculate $$\phi $$ ϕ meson transverse momentum spectra in $$\mathrm{p}+\mathrm{p}$$ p + p collisions as well as their nuclear suppressions in central $$\mathrm{A}+\mathrm{A}$$ A + A collisions both at the RHIC and the LHC in LO and NLO with the QCD ...

Semi- and Dileptonic Top Pair Decays at the ATLAS Experiment [PDF]

open access: yes, 2008
The Large Hadron Collider, starting in 2008, will be a "top factory" as top-antitop pairs will be produced with a cross section of about 830 pb at an instantaneous luminosity of 10^33 cm^-2 s^-1 during the first year. With about 30% probability top pairs

Distortions in the negative energy Dirac sea: Violation of the Gottfried sum rule and Du in the proton [PDF]

open access: yes, 2001
We report on recent work concerning the effect which the change in vacuum structure (negative energy Dirac sea), in the presence of a confining scalar field, has on the nucleon structure functions and parton distributions. Using the Dirac equation in 1+1
