30	<h2>Beam Parameters</h2>
31
32	The settings on this page relate to the beam identities and energies,
33	to a beam momentum spread and to a beam interaction spot.
34	As always, momenta and energies are to be given in units of GeV,
35	and of space and time in mm.
36
37	<h3>Incoming beams</h3>
38
39	There are two ways to set the identities and energies of the two incoming
40	beam particles. One is to use the <code>init()</code> method with no
41	arguments. Then the settings variables below will be read and used. The
42	alternative is to call <code><?php $filepath = $_GET["filepath"];
43	echo "<a href='ProgramFlow.php?filepath=".$filepath."' target='page'>";?>init(...)</a></code>
44	with arguments that provide this information. Then you need not use the
45	variables below (although it would still be possible). Note that, if nothing
46	is done, you will default to LHC at 14 TeV.
47
48	<p/>
49	Currently the beam particles must be either a hadron pair or a lepton
50	pair. In the former category <i>p p</i> and <i>pbar p</i>
51	combinations dominate, but it is also possible to combine with
52	<i>pi^+</i>, <i>pi^-</i> and <i>pi^0</i>. In the latter
53	<i>e^+ e^-</i> and <i>mu^+ mu^-</i> would be the most useful
54	combinations, but also others should work if combined with an
55	appropriate hard process.

63	here mainly for debug purposes),
64	<br/><i>11 = e^-</i>, <i>-11 = e^+</i>,
65	<br/><i>13 = mu^-</i>, <i>-13 = mu^+</i>,
66	<br/>and a few more leptons/neutrinos in a few combinations.

170
171	<h3>Beam momentum spread</h3>
172
173	This framework currently is intended for a modest beam spread, such as
174	experienced at hadron colliders. Thus it can be safely assumed that the
175	physics does not change over the CM energy range probed, so that the
176	parameters of the physics initialization at the nominal energy can be
177	used as is. Currently it can <b>not</b> be used for the more extensive
178	energy spread expected at linear <i>e^+ e^-</i> colliders. Also,
179	any attempt to combine it with external Les Houches input of
180	parton-level events is at own risk.
181
182	<p/>
183	On this page you can set the momentum spread according to a simple
184	Gaussian distribution. If you instead want a more sophisticated
185	parametrization, you can write and link your own
186	<code><?php $filepath = $_GET["filepath"];
187	echo "<a href='BeamShape.php?filepath=".$filepath."' target='page'>";?>BeamShape</a></code> class.
188
189	<br/><br/><strong>Beams:allowMomentumSpread</strong> <input type="radio" name="17" value="on"><strong>On</strong>
190	<input type="radio" name="17" value="off" checked="checked"><strong>Off</strong>
191	(<code>default = <strong>off</strong></code>)<br/>
192	Allow the beam momenta to be smeared around their initialization
193	nominal values.

250	<h3>Beam interaction vertex</h3>
251
252	On this page you can set the spread of the interaction vertex according to
253	a simple Gaussian distribution. If you instead want a more sophisticated
254	parametrization, you can write and link your own
255	<code><?php $filepath = $_GET["filepath"];
256	echo "<a href='BeamShape.php?filepath=".$filepath."' target='page'>";?>BeamShape</a></code> class.

259	<input type="radio" name="26" value="off" checked="checked"><strong>Off</strong>

261	Allow the interaction vertex of the two colliding beams to be smeared.
262	If off, then the vertex is set to be the origin.

281	The triply Gaussian distribution of interaction vertex position
282	<i>(x, y, z)</i> is restricted to a maximal total deviation from the
283	origin, like
284	<br/><i>
285	x^2/sigma_x^2 + y^2/sigma_y^2 + z^2/sigma_z^2 < maxDevVertex^2
286	</i><br/>

292	The width of a Gaussian distribution of the collision time (in units of
293	mm/c). Note that, if the above space parametrization is viewed as the
294	effect of two incoming beams along the <i>+-z</i> axis, with each beam
295	having a Gaussian spread, then the spread of the time would also become
296	a Gaussian with the same width as the <i>z</i> one (times the
297	velocity of the beams, which we expect is close to unity). For flexibility
298	we have not enforced any such relation, however.
299

302	The collision time is restricted to be in the range
303	<i>\|t\| < sigma_t * maxDevTime</i>.
304
305
306	<p/>
307	The distributions above are all centered at the origin. It is also
308	possible to shift the above distributions to be centered around another
309	nominal position. You must have <code>Beams:allowVertexSpread = on</code>
310	to use this possibility.
