On a possible violation of the optical theorem
in LHC experiments
M Kupczynski – arxive:1308.1447
[hep-phy]
Abstract: …The impossibility of
scattering phenomena without the existence of the elastic
channel is considered to be a part of the
quantum magic. However if one takes seriously
the idea that the
hadrons are extended particles one may define a unitary S matrix such
that one cannot prove
the optical theorem. In this paper we recall these results and
we give the
additional arguments why the optical theorem may be violated in LHC.
Scattering of extended
hadrons and time-reversal invariance
M Kupczynski - Hadronic J 9. 215-218 (1986)
Abstract: An unconventional description of scattering of
extended hadrons is
proposed which could shed some light on the meaning of the recently published
data
indicating a violation of the time-reversal invariance of nuclear reactions…
Purity tests for π-d charge multiplicity
distributions - Springer
J.Gajewski and M.Kupczynski,
Lett. al Nuovo
Cimento,26,81-87 (1979)
Abstract: Various purity tests of the multi- prong distribution obtained
from emulsion are performed..
The optical theorem, a purity of the
initial states and the rising total cross-sections
M Kupczyński – Czech. J.Phys. B27, 17-28
(1977)
Abstract A possibility of the violation of the
optical theorem at high energies due to the mixed
character of the initial states is discussed. A close connection of this idea
with the MIT—bag
model of hadrons is shown. The experimental evidence for the validity of the optical ...
On some important statistical tests
M Kupczynski - La Rivista del Nuovo Cimento,
7, 215-227(1977)
Abstract: Recently the need for more accurate tests of the purity of the
initial ensemble of states has
been pointed out [1, 2]. In this paper we want to review some slightly less
known among
physicists theorems from the mathematical statistics and the statistical tests
based on them ...
Tests for the purity of the
initial ensemble of states in scattering experiments
M Kupczynski - Lett. Nuovo Cimento, 11, 121-124 (1974)
Abstract:Recently a hypothesis was formulated (1) that the initial
ensemble of two-particle states E is
a mixed quantum ensemble with respect to the set of quantum numbers={S, A, l,
a}, where S
denotes the total invariant spin, A its projection on the direction of the
total linear ...
New description of the initial
states
M Kupczyński - Lett. Nuovo Cimento, 11, 117-120 (1974)
Description: It is shown that if the initial states are a particular mixed state
then one can have
a unitary S matrix and the violation of the optical theorem.
Unitarity
without the optical theorem
M Kupczyński – Lett. Nuovo Cimento , 9, 134-136 (1974)
Abstract:The general belief is
that the unitarity of the S-matrix necessarily
implies the optical theorem.
The unitarity of the S-matrix is derived from the
conservation of probability. The conservation
of probability is an obvious and unquestionable truth, so the optical theorem
is believed to ...
Is the optical theorem violated?
M Kupczyński - Physics Letters 47B, 244-246 (1973)
Abstract: In this letter we analyse pp,
πp,πd, Kp and Kd
data to check the hypothesis of
the break of the optical theorem
presented in our previous paper.
M Kupczyński - Warsaw
University preprint IFT/71/15, 1971
Abstract: Some misunderstandings
concerning the additivity assumption in the quark
model are explained..
New relativistic the “ additivity
without spectators” assumption is formulated…
It is shown that all the
speculation as to which is the additivity frame are
misleading.
