Hadron production through Higgs decay at next-to-leading order in the general-mass variable-flavor-number scheme
S. Mohammad Moosavi Nejad
It is known that about of all Higgses produced at the CERN-LHC decay into a pair of bottom quarks. Bottoms quickly hadronize, in most cases, into bottom-flavored (B) hadrons…
Zh Production, a Tool to Constrain 2HDM
Zeynab Bozorgtabar, Saeid Paktinat Mehdiabadi
Since the SM Higgs boson, h, is the superposition of two unequal-mass neutral Higgs bosons in 2HDM, therefore the associated production cross section for h and Z in SM and 2HDM can…
QCD analysis of structure functions in deep-inelastic scattering: Mellin transform by Gegenbauer polynomial up to NLO approximation
Fatemeh Arbabifar, Nader Morshedian, Leila Ghasemzadeh +1
This paper provides a thorough examination of the structure functions in deep-inelastic scattering through a comprehensive QCD analysis. Our approach harnesses sophisticated…
Vector dark matter and LHC constraints, including a 95 GeV light Higgs boson
Seyed Yaser Ayazi, Mojtaba Hosseini, Saeid Paktinat Mehdiabadi +1
We study LHC searches for an extension of the Standard Model (SM) by exploiting an additional Abelian gauge symmetry and a complex scalar Higgs portal. As the scalar is ch…
Recent data analysis to revisit the spin structure function of nucleon in Laplace space
Hoda Nematollahi, Abolfazl Mirjalili, Shahin Atashbar Tehrani
Considering a fixed-flavor number scheme and based on laplace transdormation, we perform a leading-order and next-to-leading-order QCD analysis which are including world data on po…
Parton distribution functions and QCD coupling constant from LHC and non-LHC data
Majid Azizi, Ali Khorramian, Saeid Paktinat Mehdiabadi
We present a new QCD analysis of parton distribution functions (PDFs) at the next-to-leading order (NLO) and next-to-next-to-leading order (NNLO). In the present paper, the role of…
