Direct measurement of the Higgs self-coupling in
Junya Nakamura, Ambresh Shivaji
A new method to measure the trilinear Higgs self-coupling in a single Higgs production process is proposed. Time-reversal-odd (T-odd) asymmetries in the process $e^+_{}e^-…
Boosting the invisibles searches with boson polarization
Dorival Goncalves, Junya Nakamura
It is argued that, in invisibles searches with associated production at the LHC, the signal efficiency can be sensibly improved via a detailed study of the…
Role of the polarization in the measurement
Dorival Goncalves, Junya Nakamura
It is widely known that the production channel provides a promising probe to the decay at the LHC, when the Higgs and the bosons are highly booste…
A set of new observables in the process
Junya Nakamura
Consequences of non-standard Higgs couplings in the final-state distributions of the process are studied. We derive an analytic expression for the differenti…
Polarisations of the and bosons in the processes and
Junya Nakamura
The boson in the process and the and in the process can be in polarised states. The polarisation density matrix of the ($…
Jet azimuthal angle correlations in the production of a Higgs boson pair plus two jets at hadron colliders
Junya Nakamura, Julien Baglio
Azimuthal angle correlations of two jets in the process are studied. The loop induced gluon fusion (GF) sub-process and the $\mathcal{O}(α_…
A simple merging algorithm for jet angular correlation studies
Junya Nakamura
A tree level merging algorithm which guarantees the leading order (LO) accuracy of angular correlations between jets is proposed and studied. The algorithm is designed so that n-je…
Study on the azimuthal angle correlation between two jets in the top quark pair production
Kaoru Hagiwara, Junya Nakamura
An azimuthal angle correlation between the two hardest jets is studied in the ttbar production process at the 14 TeV LHC. The event samples are generated by merging the tree level…
10 GeV neutralino dark matter and light stau in the MSSM
Kaoru Hagiwara, Satyanarayan Mukhopadhyay, Junya Nakamura
It has recently been pointed out that a component of the observed gamma ray emission in the low-latitudes of Fermi Bubble has a spectral shape that can be explained by a 10 GeV dar…
TauDecay: a library to simulate polarized tau decays via FeynRules and MadGraph5
Kaoru Hagiwara, Tong Li, Kentarou Mawatari +1
TauDecay is a library of helicity amplitudes to simulate polarized tau decays, constructed in the FeynRules and MadGraph5 framework. Together with the leptonic mode, the decay libr…
Properties of 125 GeV Higgs boson in non-decoupling MSSM scenarios
Kaoru Hagiwara, Jae Sik Lee, Junya Nakamura
Tantalizing hints of the Higgs boson of mass around 125 GeV have been reported at the LHC. We explore the MSSM parameter space in which the 125 GeV state is identified as the heavi…
Diquark contributions to Top quark charge asymmetry at the Tevatron and LHC
Kaoru Hagiwara, Junya Nakamura
We study contributions of a scalar diquark particle in a color representation of anti-triplet and sextet to the top quark pair production at the Tevatron and the Large hadron colli…
