Standard Model mass spectrum in inflationary universe [PDF]

open access: yesJournal of High Energy Physics, 2017
We work out the Standard Model (SM) mass spectrum during inflation with quantum corrections, and explore its observable consequences in the squeezed limit of non-Gaussianity. Both non-Higgs and Higgs inflation models are studied in detail.

Charm mass corrections to the bottomonium mass spectrum [PDF]

open access: yesPhys.Rev. D66 (2002) 037501, 2002
The one-loop corrections to the bottomonium mass spectrum due to the finite charm mass are evaluated in the framework of the relativistic quark model. The obtained corrections are compared with the results of perturbative QCD.

Top-quark mass from the diphoton mass spectrum [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
We calculate the $$gg\rightarrow \gamma \gamma $$ g g → γ γ amplitude by including the $$t\bar{t}$$ t t ¯ bound-state effects near their mass threshold.

Anatomy of the Higgs mass spectrum [PDF]

open access: yesPhysics Letters B, 1997
We analyze the implications of a Higgs discovery on possible "new-physics" scenarios, for mH up to ~700 GeV. For this purpose we critically review lower and upper limits on the Higgs mass in the SM and in the MSSM, respectively. Furthermore, we discuss the general features of possible "heavy" (mH≳2mZ) Higgs scenarios by means of a simple heavy-fermion ...

Glueball mass spectrum [PDF]

open access: yesPhysics Letters B, 1998
A conjectured duality between supergravity and $N=\infty$ gauge theories gives predictions for the glueball masses as eigenvalues for a supergravity wave equations in a black hole geometry, and describes a physics, most relevant to a high-temeperature expansion of a lattice QCD. We present an analytical solution for eigenvalues and eigenfunctions, with

The thermodynamics of the Hagedorn mass spectrum [PDF]

open access: yesarXiv: High Energy Physics - Theory, 2006
No bootstrap assumption is needed to derive the exponential growth of the Hagedorn hadron mass spectrum: It is a consequence of the second law applied to a relativistic gas, and the relativistic equivalence between inertial mass and its heat content.

Search for structure in the $B_s^0\pi^\pm$ invariant mass spectrum [PDF]

open access: yes, 2016
The $B_s^0\pi^\pm$ invariant mass distribution is investigated in order to search for possible exotic meson states. The analysis is based on a data sample recorded with the LHCb detector corresponding to $3$ fb$^{-1}$ of $pp$ collision data at $\sqrt{s} =

Black hole mass spectrum vs spectrum of Hawking radiation [PDF]

open access: green, 1999
We consider a massive selfgravitating shell as a model for collapsing body and a null selfgravitating shell as a model for quanta of Hawking radiation. It is show that the mass-energy spectra for the body and the radiation do not match.
