The width of the higgs boson decay into two photons in framework of nmssm with CP violation: one loop approximation

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2015
The article considers the problem of the extension of standard model physics of elementary particles. We focus on nonminimal supersymmetric models. Nowadays this model is the most appropriate compared with other developed supersymmetric theories.

Prospects for Higgs and di-Higgs measurements at the ATLAS experiment

open access: yesSciPost Physics Proceedings, 2022
The large dataset of about 3000 $\rm{fb}^{-1}$ that will be collected at the High Luminosity LHC (HL-LHC) will be used to measure Higgs boson processes in detail.

Neutralino oscillations at the LHC [PDF]

open access: yesPhysical Review D, 2013
We study a supersymmetric phenomenon that can give spectacular signals at the LHC: oscillations of neutralinos. Such oscillations can be naturally realised in R-symmetric models, where additional fields are introduced as Dirac mass partners of gauginos and Higgsinos. Majorana masses for gauginos, necessarily generated from anomaly mediation, can create

Reinterpretation of LHC results for new physics : status and recommendations after run 2 [PDF]

open access: yes, 2020
We report on the status of efforts to improve the reinterpretation of searches and measurements at the LHC in terms of models for new physics, in the context of the LHC Reinterpretation Forum.

The Scattering and Neutrino Detector at the Large Hadron Collider in CERN

open access: yesPhysics, 2023
SND@LHC (Scattering Neutrino Detector at the Large Hadron Collider) is a compact and stand-alone experiment to perform measurements with neutrinos produced in the LHC in a hitherto unexplored pseudorapidity region of 7.2 < η < 8.6.

Improved luminosity determination in pp collisions at s√=7 TeV using the ATLAS detector at the LHC [PDF]

open access: yes, 2013
The luminosity calibration for the ATLAS detector at the LHC during pp collisions at s√=7 TeV in 2010 and 2011 is presented. Evaluation of the luminosity scale is performed using several luminosity-sensitive detectors, and comparisons are made of the ...

LHC upgrade and LHC-ATLAS upgrade [PDF]

open access: yesProceedings of The 4th KMI International Symposium — PoS(KMI2019), 2019
One of the most important goals in the physics programs of the Energy Frontier research is to discover hints for extensions of the Standard Model of the particle physics. The High-Luminosity Large Hadron Collider (HL-LHC) will start the operation in 2026 to sustain and extend the physics sensitivity in the new physics search at the LHC. The HL-LHC will

Luminosity determination in pp collisions at √s=7TeV using the ATLAS detector at the LHC [PDF]

open access: yes, 2011
Measurements of luminosity obtained using the ATLAS detector during early running of the Large Hadron Collider (LHC) at √s=7 TeV are presented. The luminosity is independently determined using several detectors and multiple algorithms, each having ...

Effective supersymmetry at the LHC [PDF]

open access: yesJournal of High Energy Physics, 2010
We investigate the phenomenology of Effective Supersymmetry (ESUSY) models wherein electroweak gauginos and third generation scalars have masses up to about 1~TeV while first and second generation scalars lie in the multi-TeV range. Such models ameliorate the SUSY flavor and CP problems via a decoupling solution, while at the same time maintaining ...
