α-Cluster States in Intermediate Mass Nuclei

“…We iterate (13) to get (14) The symmetry of n implies that the quantity in curly brackets is also symmetric in the interchange of kn 1 and kn. We indicate this explicitly with the notation (15) Repeated application of (13) and use of the symmetry of n leads us finally to the exact result (16) where the case n=1has already been considered in (5) with 0 0. Here, we defined as well i…”

“…Given the outstanding success of the Standard Model (SM) [3][4][5][6][7][8][9][10][11][12] point particle quantum field theory for the other three known forces, the electromagnetic, weak and strong interactions, where the non-Abelian loop corrections predicted by the 't HofftVeltman [6][7][8][9] renormalization theory for Yang-Mills fields [13] have recently been corroborated by the precision SM tests [14][15][16] at the CERN LEP Collider, we have to agree that the union of quantum mechanics and the classical theory of general relativity is one key piece of unfinished business left-over for the 21st century. At this writing, the only accepted complete treatment of quantum general relativity, superstring theory [17,18], involves [19][20][21] 1 many hitherto unseen degrees of freedom, some at masses well-beyond the Planck mass, and this latter property is understandably a bit unsettling to some.…”

“…In Refs. [35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54], we have extended the YFS methods to the SM electroweak theory and used these extended methods to achieve high precision predictions for SM processes at LEP1 and LEP2, which have played important roles in the precision SM tests of the electroweak theory [14][15][16]. Recently [55][56][57][58][59][60][61][62][63][64][65], we have made a preliminary extension of the YFS methods to soft gluon effects in the QCD sector of the SM, with an eye toward the high energy processes at the LHC.…”

Leptonic Probes of the Standard Model

“…It is a very elegant theoretical framework, which is able to describe nearly all known experimental facts in particle physics [1,2].…”

Search for the standard model Higgs boson at LEP

“…Its mass is essentially unknown, theoretical considerations give an upper limit of about 800 GeV [2]. Recent fits of electroweak parameters to the data favor a light Higgs (m H < 193 GeV at 95% confidence level) [3].…”
